We find that this formula for the acceleration due to gravity involves only the mass of earth. It does ot involve the mass of the body on which the force of gravity of earth acts. Since the acceleration due to avity does not depend on the mass of the body, all the bodies (whether heavy or light) fall with the me acceleration towards the surface of the earth. Thus, a big stone will fall with the same acceleration as small stone because the acceleration due to gravity of earth (which acts on them during their free fall) herds, if a big stone and a small stone are dropped from the roof of a house simultaneously, they Il reach the ground at the same time. Let us solve some problems now. Sample Problem 1. Calculate the value of acceleration due to gravity on the surface of the moon. (Given: ass of the moon ; Radius of moon ) Solution. The formula for calculating the acceleration due to gravity is:
