All Germanic languages are subject to the Grimm's law and Verner's law sound shifts, which originated in the Proto-Germanic language and define the basic features differentiating them from other Indo-European languages. This is assumed to have taken place in approximately the mid-first millennium BCE in
483-402: A displacement R AB , Newton's law of gravitation states that each object exerts a gravitational force on the other, of magnitude where G is the universal gravitational constant . The above statement may be reformulated in the following way: if g is the magnitude at a given location in a gravitational field, then the gravitational force on an object with gravitational mass M is This
644-405: A gravitational field . If a first body of mass m A is placed at a distance r (center of mass to center of mass) from a second body of mass m B , each body is subject to an attractive force F g = Gm A m B / r , where G = 6.67 × 10 N⋅kg ⋅m is the "universal gravitational constant ". This is sometimes referred to as gravitational mass. Repeated experiments since
805-411: A measure of the body's inertia , meaning the resistance to acceleration (change of velocity ) when a net force is applied. The object's mass also determines the strength of its gravitational attraction to other bodies. The SI base unit of mass is the kilogram (kg). In physics , mass is not the same as weight , even though mass is often determined by measuring the object's weight using
966-467: A schwa . The Middle Dutch dialect areas were affected by political boundaries. The sphere of political influence of a certain ruler often also created a sphere of linguistic influence, with the language within the area becoming more homogenous. Following the contemporary political divisions they are in order of importance: A process of standardisation started in the Middle Ages , especially under
1127-529: A spring scale , rather than balance scale comparing it directly with known masses. An object on the Moon would weigh less than it does on Earth because of the lower gravity, but it would still have the same mass. This is because weight is a force, while mass is the property that (along with gravity) determines the strength of this force. In the Standard Model of physics, the mass of elementary particles

The groove was lined with " parchment , also smooth and polished as possible". And into this groove was placed "a hard, smooth and very round bronze ball". The ramp was inclined at various angles to slow the acceleration enough so that

At more or less the same time the Ingvaeonic nasal spirant law, moving over Western Europe from west to east, led to the development of Old English (or Anglo-Saxon), Old Frisian and Old Saxon . Hardly influenced by either development, Old Dutch probably remained relatively close to the original language of

"For a stone projected is by the pressure of its own weight forced out of the rectilinear path, which by the projection alone it should have pursued, and made to describe a curve line in the air; and through that crooked way is at last brought down to the ground. And the greater the velocity is with which it is projected, the farther it goes before it falls to the Earth." Newton further reasons that if an object were "projected in an horizontal direction from
2093-513: A force from a scale or the surface of a planetary body such as the Earth or the Moon . This force keeps the object from going into free fall. Weight is the opposing force in such circumstances and is thus determined by the acceleration of free fall. On the surface of the Earth, for example, an object with a mass of 50 kilograms weighs 491 newtons, which means that 491 newtons is being applied to keep

After being encouraged by Halley, Newton decided to develop his ideas about gravity and publish all of his findings. In November 1684, Isaac Newton sent a document to Edmund Halley, now lost but presumed to have been titled De motu corporum in gyrum (Latin for "On
2415-421: A gravitational field. Newton further assumed that the strength of each object's gravitational field would decrease according to the square of the distance to that object. If a large collection of small objects were formed into a giant spherical body such as the Earth or Sun, Newton calculated the collection would create a gravitational field proportional to the total mass of the body, and inversely proportional to

Brabantian expands into small parts in the west of Limburg while its strong influence on the East Flemish of East Flanders and eastern Zeelandic Flanders weakens towards the west. In a small area in the northwest of North Brabant ( Willemstad ), Hollandic is spoken. Conventionally, the Kleverlandish dialects are distinguished from Brabantian, but there are no objective criteria apart from geography to do so. Over 5 million people live in an area with some form of Brabantian being
3059-420: A number of closely related, mutually intelligible dialects spoken in the former Old Dutch area. Where Old Dutch fragments are very hard to read for untrained Modern Dutch speakers, the various literary works of Middle Dutch are somewhat more accessible. The most notable difference between Old and Middle Dutch is in a feature of speech known as vowel reduction , whereby vowels in unstressed syllables are leveled to

It was traditionally believed to be related to the quantity of matter in a body, until the discovery of the atom and particle physics . It was found that different atoms and different elementary particles , theoretically with the same amount of matter, have nonetheless different masses. Mass in modern physics has multiple definitions which are conceptually distinct, but physically equivalent. Mass can be experimentally defined as

While a somewhat heterogeneous group of Low Franconian dialects, Limburgish has received official status as a regional language in the Netherlands and Germany, but not in Belgium. Due to this official recognition, it receives protection by chapter 2 of the European Charter for Regional or Minority Languages . Afrikaans , although to

In the 19th century, the term " Diets " was revived by Dutch linguists and historians as well, as a poetic name for Middle Dutch and its literature . Old Dutch can be discerned more or less around the same time as Old English (Anglo-Saxon), Old High German , Old Frisian , and Old Saxon . These names are derived from
3703-509: A result, when West Flemings try to talk Standard Dutch, they are often unable to pronounce the g-sound, and pronounce it similar to the h-sound. This leaves, for example, no difference between " held " (hero) and " geld " (money). Or in some cases, they are aware of the problem, and hyper-correct the "h" into a voiced velar fricative or g-sound, again leaving no difference. The West Flemish variety historically spoken in adjacent parts in France

The abbreviation oz came later from the Italian cognate onza , pronounced [ˈontsa] (now oncia , pronounced [ˈontʃa] ). Historically, in different parts of the world, at different points in time, and for different applications, the ounce (or its translation) has referred to broadly similar but still slightly different standards of mass. The international avoirdupois ounce (abbreviated oz)

As a daughter language of 17th-century Dutch dialects, Afrikaans evolved in parallel with modern Dutch, but was influenced by various other languages in South Africa. West Frisian ( Westerlauwers Fries ), along with Saterland Frisian and North Frisian , evolved from

Like several other dialect groups, both are part of a dialect continuum that continues across the national border. The Dutch Low Saxon dialect area comprises the provinces of Groningen , Drenthe and Overijssel , as well as parts of

Unlike other European nations, the Dutch chose not to follow a policy of language expansion amongst the indigenous peoples of their colonies. In the last quarter of the 19th century, however, a local elite gained proficiency in Dutch so as to meet the needs of expanding bureaucracy and business. Nevertheless,

The only convincing resolution to this question is that all bodies must fall at the same rate. A later experiment was described in Galileo's Two New Sciences published in 1638. One of Galileo's fictional characters, Salviati, describes an experiment using
4830-410: A uniform acceleration and a uniform gravitational field. Thus, the theory postulates that the force acting on a massive object caused by a gravitational field is a result of the object's tendency to move in a straight line (in other words its inertia) and should therefore be a function of its inertial mass and the strength of the gravitational field. In theoretical physics , a mass generation mechanism

Dutch was one of the official languages of South Africa until 1925, when it
5635-485: Is a balance scale , which balances the force of one object's weight against the force of another object's weight. The two sides of a balance scale are close enough that the objects experience similar gravitational fields. Hence, if they have similar masses then their weights will also be similar. This allows the scale, by comparing weights, to also compare masses. Consequently, historical weight standards were often defined in terms of amounts. The Romans, for example, used
5796-466: Is a calque of the aforementioned Roman province Germania Inferior and an attempt by early Dutch grammarians to give their language more prestige by linking it to Roman times. Likewise, Hoogduits ("High German") and Overlands ("Upper-landish") came into use as a Dutch exonym for the various German dialects used in neighboring German states. Use of Nederduytsch was popular in the 16th century but ultimately lost out over Nederlands during

Indeed, in stark contrast to its written uniformity, Dutch lacks
6118-450: Is a theory which attempts to explain the origin of mass from the most fundamental laws of physics . To date, a number of different models have been proposed which advocate different views of the origin of mass. The problem is complicated by the fact that the notion of mass is strongly related to the gravitational interaction but a theory of the latter has not been yet reconciled with the currently popular model of particle physics , known as

In such cases, the generalized equation for weight W of an object is related to its mass m by the equation W = – ma , where a is the proper acceleration of
12880-453: The torsion balance pendulum, in 1889. As of 2008 , no deviation from universality, and thus from Galilean equivalence, has ever been found, at least to the precision 10 . More precise experimental efforts are still being carried out. The universality of free-fall only applies to systems in which gravity is the only acting force. All other forces, especially friction and air resistance , must be absent or at least negligible. For example, if
13041-444: The "Galilean equivalence principle" or the " weak equivalence principle " has the most important consequence for freely falling objects. Suppose an object has inertial and gravitational masses m and M , respectively. If the only force acting on the object comes from a gravitational field g , the force on the object is: Given this force, the acceleration of the object can be determined by Newton's second law: Putting these together,
13202-518: The 14th to 15th century onward, its urban centers ( Deventer , Zwolle , Kampen , Zutphen and Doesburg ) have been increasingly influenced by the western written Dutch and became a linguistically mixed area. From the 17th century onward, it was gradually integrated into the Dutch language area. Dutch Low Saxon used to be at one end of the Low German dialect continuum . However, the national border has given way to dialect boundaries coinciding with
13363-538: The 16th century and is known as Stadsfries ("Urban Frisian"). Hollandic together with inter alia Kleverlandish and North Brabantian , but without Stadsfries, are the Central Dutch dialects . Brabantian is named after the historical Duchy of Brabant , which corresponded mainly to the provinces of North Brabant and southern Gelderland , the Belgian provinces of Antwerp and Flemish Brabant , as well as Brussels (where its native speakers have become
13524-400: The 17th century have demonstrated that inertial and gravitational mass are identical; since 1915, this observation has been incorporated a priori in the equivalence principle of general relativity . The International System of Units (SI) unit of mass is the kilogram (kg). The kilogram is 1000 grams (g), and was first defined in 1795 as the mass of one cubic decimetre of water at
13685-688: The 7th century. It was replaced in France by Old French (a Romance language with a considerable Old Frankish influence). However, the Old Franconian language did not die out at large, as it continued to be spoken in the Low Countries, and subsequently evolved into what is now called Old Low Franconian or Old Dutch in the Low Countries. In fact, Old Frankish could be reconstructed from Old Dutch and Frankish loanwords in Old French. The term Old Dutch or Old Low Franconian refers to
13846-734: The Ancient Roman uncia (meaning: a twelfth), a unit in the Ancient Roman units of measurement weighing about 27.35 grams or 0.967 of an Avoirdupois ounce, that was one-twelfth ( 1 ⁄ 12 ) of the Roman pound ( libra ). This in turn comes from Latin uno ('one'), and thus originally meant simply 'unit'. The term uncia was borrowed twice: first into Old English as ynsan or yndsan from an unattested Vulgar Latin form with ts for c before i ( palatalization ), which survives in modern English as inch , and
14007-417: The Dutch adult population spoke a dialect or regional language on a regular basis, but in 2011, that was no more than 11 percent. In 1995, 12 percent of children of primary school age spoke a dialect or regional language, but in 2011, that had declined to four percent. Of the officially recognised regional languages Limburgish is spoken the most (in 2011 among adults 54%, among children 31%) and Dutch Low Saxon
14168-490: The Dutch government remained reluctant to teach Dutch on a large scale for fear of destabilising the colony. Dutch, the language of power, was supposed to remain in the hands of the leading elite. After independence, Dutch was dropped as an official language and replaced by Indonesian , but this does not mean that Dutch has completely disappeared in Indonesia: Indonesian Dutch , a regional variety of
14329-415: The Dutch standard language is largely absent, and speakers of these Dutch dialects will use German or French in everyday speech. Dutch is not afforded legal status in France or Germany, either by the central or regional public authorities, and knowledge of the language is declining among younger generations. As a foreign language , Dutch is mainly taught in primary and secondary schools in areas adjacent to
14490-531: The Dutch standard language, it is not mutually intelligible with Dutch and considered a sister language of Dutch, like English and German. Approximate distribution of native Dutch speakers worldwide: Dutch is an official language of the Netherlands proper (not enshrined in the constitution but in administrative law ), Belgium, Suriname, the Dutch Caribbean municipalities (St. Eustatius, Saba and Bonaire), Aruba , Curaçao and Sint Maarten . Dutch
14651-408: The Dutch, was still spoken by about 500,000 half-blood in Indonesia in 1985. Yet the Indonesian language inherited many words from Dutch: words for everyday life as well as scientific and technological terms. One scholar argues that 20% of Indonesian words can be traced back to Dutch words, many of which are transliterated to reflect phonetic pronunciation e.g. kantoor "office" in Indonesian
14812-618: The English mints, the principal one being in the Tower of London. It dates back to the Anglo-Saxon coinage weight standard. It was abolished in favour of the Troy ounce by Henry VIII in 1527. An ounce-force is 1 ⁄ 16 of a pound-force, or about 0.2780139 newtons . It is defined as the force exerted by a mass of one avoirdupois ounce under standard gravity (at the surface of the earth, its weight ). The "ounce" in "ounce-force"
14973-602: The Franks. However, the language did experience developments of its own, such as very early final-obstruent devoicing . In fact, the find at Bergakker indicates that the language may already have experienced this shift during the Old Frankish period. Attestations of Old Dutch sentences are extremely rare. The language is mostly recorded on fragmentary relics, and words have been reconstructed from Middle Dutch and loan words from Old Dutch in other languages. The oldest recorded
15134-675: The Kilogram (IPK) in 1889. However, the mass of the IPK and its national copies have been found to drift over time. The re-definition of the kilogram and several other units came into effect on 20 May 2019, following a final vote by the CGPM in November 2018. The new definition uses only invariant quantities of nature: the speed of light , the caesium hyperfine frequency , the Planck constant and
15295-576: The Netherlands and Flanders . In French-speaking Belgium , over 300,000 pupils are enrolled in Dutch courses, followed by over 23,000 in the German states of Lower Saxony and North Rhine-Westphalia , and about 7,000 in the French region of Nord-Pas-de-Calais (of which 4,550 are in primary school). At an academic level, the largest number of faculties of neerlandistiek can be found in Germany (30 universities), followed by France (20 universities) and
15456-412: The Netherlands and Belgium, the dialect spoken in and around the German town of Kleve ( Kleverlandish ) is historically and genetically a Low Franconian variety. In North-Western France, the area around Calais was historically Dutch-speaking (West Flemish), of which an estimated 20,000 are daily speakers. The cities of Dunkirk , Gravelines and Bourbourg only became predominantly French-speaking by
15617-539: The Netherlands, although there are recognisable differences in pronunciation, comparable to the pronunciation differences between standard British and standard American English. In 1980 the Netherlands and Belgium concluded the Language Union Treaty . This treaty lays down the principle that the two countries must gear their language policy to each other, among other things, for a common system of spelling. Dutch belongs to its own West Germanic sub-group,
15778-475: The UK, as in " 16 oz denim ". The number refers to the weight in ounces of a given amount of fabric, either a yard of a given width, or a square yard, where the depth of the fabric is a fabric-specific constant. The most common unit of measure for the copper thickness on a printed circuit board (PCB) is ounces (oz), as in mass. It is the resulting thickness when the mass of copper is pressed flat and spread evenly over
15939-674: The United Kingdom (5 universities). Despite the Dutch presence in Indonesia for almost 350 years, as the Asian bulk of the Dutch East Indies , the Dutch language has no official status there and the small minority that can speak the language fluently are either educated members of the oldest generation, or employed in the legal profession such as historians, diplomats, lawyers, jurists and linguists/polyglots, as certain law codes are still only available in Dutch. Dutch
16100-416: The United States. In the United Kingdom it ceased to be an independent unit of measure in 2000, but may still be seen as an (imprecise) indicator of portion sizes in burger and steak restaurants. A troy ounce (abbreviated oz t) is equal to 480 grains . Consequently, the international troy ounce is equal to exactly 31.1034768 grams. There are 12 troy ounces in the now obsolete troy pound . Today,
16261-621: The West Indies, slaves were forbidden to speak Dutch, with the effect that local creoles such as Papiamento and Sranan Tongo which were based not on Dutch but rather other European languages, became common in the Dutch West Indies. However, as most of the people in the Colony of Surinam (now Suriname ) worked on Dutch plantations, this reinforced the use of Dutch as a means for direct communication. In Suriname today, Dutch
16422-428: The abstract concept of mass. There are a number of ways mass can be measured or operationally defined : In everyday usage, mass and " weight " are often used interchangeably. For instance, a person's weight may be stated as 75 kg. In a constant gravitational field, the weight of an object is proportional to its mass, and it is unproblematic to use the same unit for both concepts. But because of slight differences in
16583-661: The area known as the Low Countries goes back further in time, with the Romans referring to the region as Germania Inferior ("Lower" Germania). It is a reference to the Low Countries' downriver location at the Rhine–Meuse–Scheldt delta near the North Sea . From 1551, the designation Nederlands received strong competition from the name Nederduytsch (literally "Low Dutch", Dutch being used in its archaic sense covering all continental West Germanic languages). It
16744-457: The avoirdupois ounce is the mass measure used for most purposes, the ' troy ounce ' of exactly 31.1034768 g is used instead for the mass of precious metals such as gold, silver, platinum, palladium, rhodium, etc. The term 'ounce' is also used in other contexts: Historically, a variety of different ounces measuring mass or volume were used in different jurisdictions by different trades and at different times in history. Ounce derives from
16905-624: The borders of other standard language areas. In most cases, the heavy influence of the standard language has broken the dialect continuum . Examples are the Gronings dialect spoken in Groningen as well as the closely related varieties in adjacent East Frisia (Germany). Kleverlandish is a dialect spoken in southern Gelderland , the northern tip of Limburg , and northeast of North Brabant (Netherlands), but also in adjacent parts of North Rhine-Westphalia (Germany). Limburgish ( Limburgs )
17066-479: The case with the Gronings dialect , which is considered a variety of the Dutch Low Saxon regional language, but it is relatively distinct from other Dutch Low Saxon varieties. Also, some Dutch dialects are more remote from the Dutch standard language than some varieties of a regional language are. Within the Netherlands, a further distinction is made between a regional language and a separate language, which
17227-405: The classical theory offers no compelling reason why the gravitational mass has to equal the inertial mass. That it does is merely an empirical fact. Albert Einstein developed his general theory of relativity starting with the assumption that the inertial and passive gravitational masses are the same. This is known as the equivalence principle . The particular equivalence often referred to as
17388-553: The close of the 18th century, with (Hoog)Duytsch establishing itself as the Dutch exonym for German during this same period. In the 19th century Germany saw the rise of the categorisation of dialects, with German dialectologists terming the German dialects spoken in the mountainous south of Germany as Hochdeutsch ("High German"). Subsequently, German dialects spoken in the north were designated as Niederdeutsch ("Low German"). The names for these dialects were calqued by Dutch linguists as Nederduits and Hoogduits . As
17549-413: The course of fifteen centuries. During that period, they forced Old Frisian back from the western coast to the north of the Low Countries, and influenced or even replaced Old Saxon spoken in the east (contiguous with the Low German area). On the other hand, Dutch has been replaced in adjacent lands in present-day France and Germany. The division into Old, Middle and Modern Dutch is mostly conventional, since
17710-540: The declaration of independence of Indonesia, Western New Guinea , the "wild east" of the Dutch East Indies , remained a Dutch colony until 1962, known as Netherlands New Guinea . Despite prolonged Dutch presence, the Dutch language is not spoken by many Papuans, the colony having been ceded to Indonesia in 1963. Dutch-speaking immigrant communities can also be found in Australia and New Zealand. The 2011 Australian census showed 37,248 people speaking Dutch at home. At
17871-603: The development of a separate Dutch language. It was spoken by the descendants of the Salian Franks who occupied what is now the southern Netherlands , northern Belgium , part of northern France, and parts of the Lower Rhine regions of Germany. The High German consonant shift, moving over Western Europe from south to west, caused a differentiation with the Central and High Franconian in Germany. The latter would as
18032-474: The devil? ... I forsake the devil"). If only for its poetic content, the most famous Old Dutch sentence is probably Hebban olla vogala nestas hagunnan, hinase hic enda tu, wat unbidan we nu ("All birds have started making nests, except me and you, what are we waiting for"), is dated to around the year 1100, written by a Flemish monk in a convent in Rochester , England . Since the sentence speaks to
18193-470: The double of the distance between the two bodies. Hooke urged Newton, who was a pioneer in the development of calculus , to work through the mathematical details of Keplerian orbits to determine if Hooke's hypothesis was correct. Newton's own investigations verified that Hooke was correct, but due to personal differences between the two men, Newton chose not to reveal this to Hooke. Isaac Newton kept quiet about his discoveries until 1684, at which time he told
18354-434: The elapsed time could be measured. The ball was allowed to roll a known distance down the ramp, and the time taken for the ball to move the known distance was measured. The time was measured using a water clock described as follows: Galileo found that for an object in free fall, the distance that the object has fallen is always proportional to the square of the elapsed time: Galileo had shown that objects in free fall under
18515-489: The end of the 19th century. In the countryside, until World War I , many elementary schools continued to teach in Dutch, and the Catholic Church continued to preach and teach the catechism in Dutch in many parishes. During the second half of the 19th century, Dutch was banned from all levels of education by both Prussia and France and lost most of its functions as a cultural language. In both Germany and France,
18676-497: The exact number of carob seeds that would be required to produce a gravitational field similar to that of the Earth or Sun. In fact, by unit conversion it is a simple matter of abstraction to realize that any traditional mass unit can theoretically be used to measure gravitational mass. Measuring gravitational mass in terms of traditional mass units is simple in principle, but extremely difficult in practice. According to Newton's theory, all objects produce gravitational fields and it
18837-410: The feather should hit the ground at exactly the same time (assuming the acceleration of both objects towards each other, and of the ground towards both objects, for its own part, is negligible). This can easily be done in a high school laboratory by dropping the objects in transparent tubes that have the air removed with a vacuum pump. It is even more dramatic when done in an environment that naturally has
18998-404: The first celestial bodies observed to orbit something other than the Earth or Sun. Galileo continued to observe these moons over the next eighteen months, and by the middle of 1611, he had obtained remarkably accurate estimates for their periods. Sometime prior to 1638, Galileo turned his attention to the phenomenon of objects in free fall, attempting to characterize these motions. Galileo was not
19159-402: The first paragraph of Principia , Newton defined quantity of matter as “density and bulk conjunctly”, and mass as quantity of matter. The quantity of matter is the measure of the same, arising from its density and bulk conjunctly. ... It is this quantity that I mean hereafter everywhere under the name of body or mass. And the same is known by the weight of each body; for it is proportional to
19320-436: The first to investigate Earth's gravitational field, nor was he the first to accurately describe its fundamental characteristics. However, Galileo's reliance on scientific experimentation to establish physical principles would have a profound effect on future generations of scientists. It is unclear if these were just hypothetical experiments used to illustrate a concept, or if they were real experiments performed by Galileo, but
19481-572: The gap between Galileo's gravitational acceleration and Kepler's elliptical orbits. It appeared in Newton's 1728 book A Treatise of the System of the World . According to Galileo's concept of gravitation, a dropped stone falls with constant acceleration down towards the Earth. However, Newton explains that when a stone is thrown horizontally (meaning sideways or perpendicular to Earth's gravity) it follows
19642-421: The gravitational acceleration is given by: This says that the ratio of gravitational to inertial mass of any object is equal to some constant K if and only if all objects fall at the same rate in a given gravitational field. This phenomenon is referred to as the "universality of free-fall". In addition, the constant K can be taken as 1 by defining our units appropriately. The first experiments demonstrating
19803-415: The imagination, it is often erroneously stated as the oldest Dutch sentence. Old Dutch naturally evolved into Middle Dutch . The year 1150 is often cited as the time of the discontinuity, but it actually marks a time of profuse Dutch writing; during this period a rich Medieval Dutch literature developed. There was at that time no overarching standard language ; Middle Dutch is rather a collective name for
19964-711: The influence of the Burgundian Ducal Court in Dijon ( Brussels after 1477). The dialects of Flanders and Brabant were the most influential around this time. The process of standardisation became much stronger at the start of the 16th century, mainly based on the urban dialect of Antwerp . The 1585 fall of Antwerp to the Spanish army led to a flight to the northern Netherlands, where the Dutch Republic declared its independence from Spain. This influenced
20125-629: The influence of the Earth's gravitational field have a constant acceleration, and Galileo's contemporary, Johannes Kepler, had shown that the planets follow elliptical paths under the influence of the Sun's gravitational mass. However, Galileo's free fall motions and Kepler's planetary motions remained distinct during Galileo's lifetime. According to K. M. Browne: "Kepler formed a [distinct] concept of mass ('amount of matter' ( copia materiae )), but called it 'weight' as did everyone at that time." Finally, in 1686, Newton gave this distinct concept its own name. In
20286-563: The language now known as Dutch. In the Low Countries Dietsch or its Early Modern Dutch form Duytsch as an endonym for Dutch gradually went out of common use and was gradually replaced by the Dutch endonym Nederlands . This designation (first attested in 1482) started at the Burgundian court in the 15th century, although the use of neder , laag , bas , and inferior ("nether" or "low") to refer to
20447-629: The least (adults 15%, children 1%). The decline of the West Frisian language in Friesland occupies a middle position (adults 44%, children 22%). Dialects are most often spoken in rural areas, but many cities have a distinct city dialect. For example, the city of Ghent has very distinct "g", "e" and "r" sounds that greatly differ from its surrounding villages. The Brussels dialect combines Brabantian with words adopted from Walloon and French . Some dialects had, until recently, extensions across
20608-424: The measurable mass of an object increases when energy is added to it (for example, by increasing its temperature or forcing it near an object that electrically repels it.) This motivates a search for a different definition of mass that is more accurate than the traditional definition of "the amount of matter in an object". Dutch language Dutch ( endonym : Nederlands [ˈneːdərlɑnts] )
20769-437: The modern standard languages . In this age no standard languages had yet developed, while a perfect West Germanic dialect continuum remained present; the division reflects the contingent future contribution dialect groups would have to the later languages. The early form of Dutch was a set of Franconian dialects spoken by the Salian Franks in the 5th century. These happened to develop through Middle Dutch to Modern Dutch over
20930-558: The motion of bodies in an orbit"). Halley presented Newton's findings to the Royal Society of London, with a promise that a fuller presentation would follow. Newton later recorded his ideas in a three-book set, entitled Philosophiæ Naturalis Principia Mathematica (English: Mathematical Principles of Natural Philosophy ). The first was received by the Royal Society on 28 April 1685–86; the second on 2 March 1686–87; and
21091-403: The nearby gravitational field. No matter how strong the gravitational field, objects in free fall are weightless , though they still have mass. The force known as "weight" is proportional to mass and acceleration in all situations where the mass is accelerated away from free fall. For example, when a body is at rest in a gravitational field (rather than in free fall), it must be accelerated by
21252-509: The object caused by all influences other than gravity. (Again, if gravity is the only influence, such as occurs when an object falls freely, its weight will be zero). Although inertial mass, passive gravitational mass and active gravitational mass are conceptually distinct, no experiment has ever unambiguously demonstrated any difference between them. In classical mechanics , Newton's third law implies that active and passive gravitational mass must always be identical (or at least proportional), but
21413-430: The object from going into free fall. By contrast, on the surface of the Moon, the same object still has a mass of 50 kilograms but weighs only 81.5 newtons, because only 81.5 newtons is required to keep this object from going into a free fall on the moon. Restated in mathematical terms, on the surface of the Earth, the weight W of an object is related to its mass m by W = mg , where g = 9.80665 m/s
21574-412: The orbit of Earth's Moon), or it can be determined by measuring the gravitational acceleration on the Earth's surface, and multiplying that by the square of the Earth's radius. The mass of the Earth is approximately three-millionths of the mass of the Sun. To date, no other accurate method for measuring gravitational mass has been discovered. Newton's cannonball was a thought experiment used to bridge
21735-470: The original Dutch language version dating from colonial times remains the authoritative version. Up to half a million native speakers reside in the United States, Canada and Australia combined, and historical linguistic minorities on the verge of extinction remain in parts of France and Germany. Dutch is one of the closest relatives of both German and English, and is colloquially said to be "roughly in between" them. Dutch, like English, has not undergone
21896-409: The planets orbit the Sun. In Kepler's final planetary model, he described planetary orbits as following elliptical paths with the Sun at a focal point of the ellipse . Kepler discovered that the square of the orbital period of each planet is directly proportional to the cube of the semi-major axis of its orbit, or equivalently, that the ratio of these two values is constant for all planets in
22057-527: The predominant colloquial language out of the area's 22 million Dutch-speakers. Limburgish , spoken in both Belgian Limburg and Netherlands Limburg and in adjacent parts in Germany, is considered a dialect in Belgium, while having obtained the official status of regional language in the Netherlands. Limburgish has been influenced by the Ripuarian varieties like the Colognian dialect , and has had
22218-400: The presence of an applied force. The inertia and the inertial mass describe this property of physical bodies at the qualitative and quantitative level respectively. According to Newton's second law of motion , if a body of fixed mass m is subjected to a single force F , its acceleration a is given by F / m . A body's mass also determines the degree to which it generates and is affected by
22379-411: The provinces of Gelderland , Flevoland , Friesland and Utrecht . This group, which is not Low Franconian but instead Low Saxon and close to neighbouring Low German, has been elevated by the Netherlands (and by Germany) to the legal status of streektaal ( regional language ) according to the European Charter for Regional or Minority Languages . It is regarded as Dutch for a number of reasons. From
22540-464: The relative gravitation mass of each object. Mass was traditionally believed to be a measure of the quantity of matter in a physical body, equal to the "amount of matter" in an object. For example, Barre´ de Saint-Venant argued in 1851 that every object contains a number of "points" (basically, interchangeable elementary particles), and that mass is proportional to the number of points the object contains. (In practice, this "amount of matter" definition
22701-515: The rest of the text lack any consensus. The Franks emerged in the southern Netherlands ( Salian Franks ) and central Germany ( Ripuarian Franks ), and later descended into Gaul . The name of their kingdom survives in that of France. Although they ruled the Gallo-Romans for nearly 300 years, their language, Frankish , became extinct in most of France and was replaced by later forms of the language throughout Luxembourg and Germany in around
22862-554: The results obtained from these experiments were both realistic and compelling. A biography by Galileo's pupil Vincenzo Viviani stated that Galileo had dropped balls of the same material, but different masses, from the Leaning Tower of Pisa to demonstrate that their time of descent was independent of their mass. In support of this conclusion, Galileo had advanced the following theoretical argument: He asked if two bodies of different masses and different rates of fall are tied by
23023-423: The rights of Dutch speakers, mostly referred to as "Flemish". However, the dialect variation was a serious disadvantage in the face of the standardised francophony . Since standardisation is a lengthy process, Dutch-speaking Belgium associated itself with the standard language that had already developed in the Netherlands over the centuries. Therefore, the situation in Belgium is essentially no different from that in
23184-524: The same branch of the West Germanic languages as Old English (i.e. Anglo-Frisian ) and are therefore genetically more closely related to English and Scots than to Dutch. The different influences on the respective languages, however, particularly that of Norman French on English and Dutch on West Frisian, have rendered English quite distinct from West Frisian, and West Frisian less distinct from Dutch than from English. Although under heavy influence of
23345-503: The same common mass standard, the carob seed. The ratio of a Roman ounce (144 carob seeds) to a Roman pound (1728 carob seeds) was: In 1600 AD, Johannes Kepler sought employment with Tycho Brahe , who had some of the most precise astronomical data available. Using Brahe's precise observations of the planet Mars, Kepler spent the next five years developing his own method for characterizing planetary motion. In 1609, Johannes Kepler published his three laws of planetary motion, explaining how
23506-407: The same thing. Humans, at some early era, realized that the weight of a collection of similar objects was directly proportional to the number of objects in the collection: where W is the weight of the collection of similar objects and n is the number of objects in the collection. Proportionality, by definition, implies that two values have a constant ratio : An early use of this relationship
23667-455: The set of Franconian dialects (i.e. West Germanic varieties that are assumed to have evolved from Frankish ) spoken in the Low Countries during the Early Middle Ages , from around the 5th to the 12th century. Old Dutch is mostly recorded on fragmentary relics, and words have been reconstructed from Middle Dutch and Old Dutch loanwords in French. Old Dutch is regarded as the primary stage in
23828-441: The square of the distance to the body's center. For example, according to Newton's theory of universal gravitation, each carob seed produces a gravitational field. Therefore, if one were to gather an immense number of carob seeds and form them into an enormous sphere, then the gravitational field of the sphere would be proportional to the number of carob seeds in the sphere. Hence, it should be theoretically possible to determine
23989-501: The strength of the Earth's gravitational field at different places, the distinction becomes important for measurements with a precision better than a few percent, and for places far from the surface of the Earth, such as in space or on other planets. Conceptually, "mass" (measured in kilograms ) refers to an intrinsic property of an object, whereas "weight" (measured in newtons ) measures an object's resistance to deviating from its current course of free fall , which can be influenced by
24150-500: The third on 6 April 1686–87. The Royal Society published Newton's entire collection at their own expense in May 1686–87. Isaac Newton had bridged the gap between Kepler's gravitational mass and Galileo's gravitational acceleration, resulting in the discovery of the following relationship which governed both of these: where g is the apparent acceleration of a body as it passes through a region of space where gravitational fields exist, μ
24311-545: The time are generally split into three dialect groups: Ingvaeonic (North Sea Germanic), Istvaeonic (Weser–Rhine Germanic) and Irminonic (Elbe Germanic). It appears that the Frankish tribes fit primarily into the Istvaeonic dialect group with certain Ingvaeonic influences towards the northwest, which are still seen in modern Dutch. The Frankish language itself is not directly attested, the only possible exception being
24472-492: The top of a high mountain" with sufficient velocity, "it would reach at last quite beyond the circumference of the Earth, and return to the mountain from which it was projected." In contrast to earlier theories (e.g. celestial spheres ) which stated that the heavens were made of entirely different material, Newton's theory of mass was groundbreaking partly because it introduced universal gravitational mass : every object has gravitational mass, and therefore, every object generates
24633-466: The transition between them was very gradual. One of the few moments when linguists can detect something of a revolution is when the Dutch standard language emerged and quickly established itself. The development of the Dutch language is illustrated by the following sentence in Old, Middle and Modern Dutch: Among the Indo-European languages , Dutch is grouped within the Germanic languages , meaning it shares
24794-421: The troy ounce is used only to express the mass of precious metals such as gold , platinum , palladium , rhodium or silver . Bullion coins are the most common products produced and marketed in troy ounces, but precious metal bars also exist in gram and kilogram (kg) sizes.

He further stated that gravitational attraction increases by how much nearer the body wrought upon is to its own center. In correspondence with Isaac Newton from 1679 and 1680, Hooke conjectured that gravitational forces might decrease according to
