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)
What do you mean by buoyancy?
When does an object float or sink when placed on the surface of water?
How does the force of gravitation between two bodies change when the distance between them is reduced to half?
Gravitational force acts on all objects in proportion to their masses. Why, then, does not a heavy object fall faster than a light object?
