Explain the term ‘gravity’.
the Earth. Force gravity acting on a body is the measure of the weight of the body. A ball released from some height falls towards the surface of the Earth because of the Earth’s gravity. Gravity of different bodies in the universe is different. Gravity is decided by its acceleration. Acceleration due to gravity is given by,
Where, M is the mass of the Earth.
r is the radius of the Earth.
G is the universal gravitation constant.
