Question

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?

Answer 1

if one measures displacement in the vertical, and velocity in the direction it is going, then at the bottom position, vertical displacement is zero, and velocity is maximum.
