During the S.H.M of simple pendulum, when the bob comes back to its mean position, the displacement gradually decreases, and eventully becomes zero at the equilibrium position, while it is said that its velocity is still maximum despite of zero displacement, then how is it possible for a body to have max.velocity with zero dis?
