The results of the Cavendish Experiment was the mass density of the earth , yet others were able to derive the actual value of the gravitational constant from the experiments results.
What did the Cavendish experiment prove?
The experiment was originally devised to determine Earth’s density . ... The Cavendish experiment was significant not only for measuring Earth’s density (and thus its mass) but also for proving that Newton’s law of gravitation worked on scales much smaller than those of the solar system.
How did Cavendish discover G?
In 1798 Cavendish measured the force between attracting lead spheres with a torsion balance . He knew the masses of the spheres and how far apart they were. He carefully measured the force between them, which allowed him to calculate G.
What did Henry Cavendish discover about the atom?
He is noted for his discovery of hydrogen , which he termed “inflammable air”. He described the density of inflammable air, which formed water on combustion, in a 1766 paper, On Factitious Airs. Antoine Lavoisier later reproduced Cavendish’s experiment and gave the element its name.
Why does Cavendish use torsion balance?
The answer to this problem came from Henry Cavendish in 1798, when he performed experiments with a torsion balance, measuring the gravitational attraction between relatively small objects in the laboratory . The value he determined for G allowed the mass and density of the Earth to be deter- mined.
Who found the value of G?
The constant of proportionality in this equation is G – the universal gravitation constant. The value of G was not experimentally determined until nearly a century later (1798) by Lord Henry Cavendish using a torsion balance.
Who discovered gravity?
Physically, Sir Isaac Newton was not a large man. However, he had a large intellect, as shown by his discoveries on gravity, light, motion, mathematics, and more. Legend has it that Isaac Newton came up with gravitational theory in 1665, or 1666, after watching an apple fall.
What did Cavendish discover about water?
Henry Cavendish (10 October 1731 – 24 February 1810) was a British natural philosopher and theoretical chemist and physicist. Cavendish described the density of inflammable air, in a 1766 paper “On Factitious Airs” where he noted it formed water on combustion and is considered as the discovery of hydrogen .
How did Henry Cavendish change the world?
Cavendish was distinguished for great accuracy and precision in research into the composition of atmospheric air , the properties of different gases, the synthesis of water, the law governing electrical attraction and repulsion, a mechanical theory of heat, and calculations of the density (and hence the weight) of Earth ...
What is value of g?
In the first equation above, g is referred to as the acceleration of gravity. Its value is 9.8 m/s 2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s 2 .
What was Cavendish known for?
Henry Cavendish (1731–1810) was an outstanding chemist and physicist . Although he was not a major figure in the history of respiratory physiology he made important discoveries concerning hydrogen, carbon dioxide, atmospheric air, and water.
What is the definition of Cavendish?
cavendish. / (ˈkævəndɪʃ) / noun . tobacco that has been sweetened and pressed into moulds to form bars .
What was Cavendish’s chemical equation?
Answer: The reaction between zinc and HCl is given by the symbolic equation Zn + HCl → ZnCl2 + H2 .
How did the Cavendish experiment work?
The Cavendish Experiment is a clever way to measure the Gravitational Constant that is stated in the Universal Gravitation Equation. ... This experiment used a torsion balance device to attract lead balls together , measuring the torque on a wire and equating it to the gravitational force between the balls.
How did Cavendish find the density of the Earth?
The method Cavendish used to calculate the Earth’s density consists in measuring the force on a small ball caused by a large ball of known mass, and comparing it with the force on the small ball caused by the Earth , so the Earth can be calculated to be N times more massive than the large ball without the need to obtain ...
