The force which earth exerts on a body is called 'force of gravity'. i.e.

Where M = mass of the earth, R = radius of the earth.

Due to this force, a body released from some height on the earth's surface falls towards the earth with its velocity increasing at a constant rate.

**Acceleration due to Gravity :**

The acceleration produced in a body due to attraction of earth is called the acceleration due to gravity and is denoted by 'g'.

near the earth surface g on moon ≈

A body moving upwards with some initial velocity, experiences a retardation of 9.8 m/s^{2} & its velocity decreases continuously unless it becomes zero.

After this, it again starts falling towards the earth with the same acceleration of 9.8 m/s^{2}.

The value of g is minimum at equator and maximum at poles.

The value of g does not depend upon the mass of the body falling towards the earth.
