How do you calculate gravitational constant?
You measure the gravitational force between two objects - this can be done with a Cavendish balance. Then you plug in the numbers (masses, and force) into the universal formula for gravitation.
Who calculated the Universal Gravitational Constant?
Henry Cavendish
What is the symbol for the constant of universal gravitation?
G = 6.6738480x10-11 m3kg-1s-2
Who discovered universal gravitational constant?
Henry Cavendish with about 1.19% error. He measured it to be 6.754 × 10−11N-m2/kg2.
What is the dimension of gravitation constant?
what is dimnsion of gravitational constant
What country did cavendish develop the universal constant of gravitation?
England.
What apparatus was used by Cavendish to discover the universal gravitation constant (G)?
The gravitational constant denoted by letter G, is an empirical physical constant involved in the calculation(s) of gravitational force between two bodies
What apparatus did Cavendish use to find a value for newton's universal gravitational?
Cavendish used a torsion balance apparatus, known as the Cavendish experiment, to determine the value for Newton's universal gravitational constant. The apparatus consists of a light rod suspended from a thin wire, with two small lead spheres mounted on either end of the rod. By measuring the twisting of the wire due to the gravitational force between the spheres, Cavendish was able to calculate the value of the gravitational constant.

What was Cavendishs contribution to Newtons Law of Gravitation?
Henry Cavendish's contribution to Newton's Law of Gravitation was his experiment to determine the gravitational constant, which allowed for the precise calculation of the gravitational force between two objects. This value was crucial for the accurate prediction of the behavior of celestial bodies based on Newton's law of gravitation.
What is the formula needed to measure the earth's mass?
You use the universal formula for gravitation. Lab measurements - such as the Cavendish balance - are used to determine the constant, G. Once this is known, you can measure the force of gravity between a known mass, and Earth, and insert the values in the formula for gravitation.
Who determined the value of the universal gravitational constant experimentally for the first time?
Cavendish
Is universal gravitation is constant on moon as on earth?
Yes, the universal gravitational constant is believed to be the same across the whole of the universe.
What has the author B A Soldano written?
B. A. Soldano has written: 'Newton's law of universal gravitation and the fine structure constant' -- subject(s): Fine-structure constant, Gravitation
What is the symbol for the constant of universal gravitation?
G = 6.6738480x10-11 m3kg-1s-2
Why is it necessary to use the universal gravitation constant in the universal law of gravitation?
To rationalize the units on both sides of the equation, E= -GmM/r, e.g if feet is used as the unit of distance r then the Constant G would have a different value.
