thevalueof`S,theaccelerationduetogravitySolution
Theaccelerationduetogravityof earthistherateofincreaseofvelocityofabody fallingfreelytowardstheearth.Atagivenplace, the value of acceleration due to gravity is constant but it varies from one place to another place on the earth surface. It is due to this fact thatearthisnotaperfectsphere.Itisflattenedat the poles and bulges out at the equator. The value of 'g' is minimum at the equator and maximum at the poles
