The gravitational constant mentioned by Newton was measured at the end of the 18th century by Henry Cavendish (in the Cavendish experiment), using a torsion balance or pendulum designed by Mitchell which measured the force between suspended lead balls, which twisted (or applied torque) to a bar, the magnitude of which is proportional to the force applied. His intent was to detemine the specific gravity of the earth, but his notes indicate a value for G which differs by only about 1% from the value accepted today.

Difference between electric forces and gravitational forces is that electrical forces include?
In case of electric force there are both repulsive and attractive. But in case of gravitational force, only attractive force. Electrical force between electric charges. Gravitational force between masses. In electric force we use a constant known as permittivity of the medium. But in gravitational force a universal constant known as Gravitational constant is used. Electrical force is very much greater than gravitational force.
What phase of the moon does it have the strongest gravitational pull?
The gravitational pull of the moon, on the earth, is almost a constant - whatever its phase.
IS the gravitaional constant of moon is same as earth?
Yes. All astronomical observations to date suggest that the gravitational constant is literally a universal constant ... the same everywhere in the universe.
What is the force between the earth and a body on earth?
The gravitational constant on Earth is 10 Newtons per kg (well exactly about 9.81 Newtons)
What makes the satellite orbit?
A satellite will orbit due to a gravitational field, which is formed by the gravitational force between the satellite and stellar body. This force is equal to the product of the gravitational constant, and the masses of both objects divided by the square of the distance separating them.
When was g the earth's gravitational constant calculated?
g, the force of the Earth's gravitational attraction, is not a constant.
Who calculated the Universal Gravitational Constant?
Henry Cavendish
Who measured the gravitational constant G?
Cavendish measured the gravitational constant "G".
Why did Einstein have to find a gravitational constant?
The gravitational constant was found by Newton, not Einstein.
Are gravitational constant and gravitational force the same thing?
No.
Why gravitational constant?
The gravitational constant was derived experimentally. Until recently, it was believed that it was a universal constant. However, developments in cosmological theories suggest the possibility that it is not a constant.
Who founded universal gravitational constant?
Sir. Isaac Newton discovered the formula with the universal gravitational constant.
What is the dimension of gravitation constant?
what is dimnsion of gravitational constant
What is a measure of the gravitational force exerted on an abject?
Force gravitational = (mass of the object)(the gravitational constant) F=mg "g" is the gravitational constant, it is equal to 9.8 m/s^2
When was gravitational constant found?
Although Newton included the gravitational constant in his law of universal gravitational constant, its value was not determined until some 70 odd years after his death, when Henry Cavendish measured it in 1798.
What is the formula for calculating weight when you know the mass?
Weight = Mass x (Local Gravitational Constant)/(Standard Gravitational COnstant)
When can you ignore the gravitational constant?
After you die
