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.

IS the gravitaional constant of moon is same as earth?

No, the gravitational constant on the Moon is not the same as on Earth. The gravitational constant depends on the mass and radius of the celestial body. The Moon has a lower mass and radius compared to Earth, resulting in a weaker gravitational constant on the Moon.


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 thrust on the rocket in the absence of gravitational force of attraction constant?

Yes, the thrust on the rocket remains constant in the absence of gravitational force. Thrust is the force pushing the rocket forward, generated by the propulsion system. It is independent of gravitational force.


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.


How was G measured?

The gravitational constant, G, was first determined by Henry Cavendish in 1798 using a torsion balance experiment. This involved measuring the gravitational force between two known masses and the distance between them to calculate G. The value of G is crucial in determining the strength of the gravitational attraction between objects.

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.
