**Earth’s Gravitational Force**

- The force which earth exerts on a body is called ‘force of gravity’. i.e.

(F=frac{GMm}})

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’.
- ( g=frac{GM}}=9.8
