How does the force of gravitation between two bodies change when the distance between them is reduced to half?
According to the law of gravitation, the force of attraction between two bodies is
What do you mean by buoyancy?
Gravitational force acts on all objects in proportion to their masses. Why, then, does not a heavy object fall faster than a light object?
When does an object float or sink when placed on the surface of water?
What is the magnitude of the gravitational force between the earth and 1 kg object on its surface? (Mass of the Earth = 6 x 104 kg and radius of earth is 6.4 x 106 m)
