The force of
attraction exerted by the earth on a body is called gravity. The acceleration
produced in the motion of a body under the effect of gravity is called acc due
to gravity. It is denote by g. It is independent of mass of the body .
1. Acc due to gravity is maximum on the surface of earth.
2. The value of on surface of earth is equal to 9.8 meter per sec square .
3. The value of g decreases with height from the surface of earth.
4. The value of g decreases with depth from the surface of earth.
5. The value of g at the centre of earth is zero. So weight is also zero at
centre of earth.
6. The value of g is greater at the poles than that at the equator.
