The hanging bob of a simple pendulum is displaced to one extreme position B and then released. It swings towards centre position A and then to the other extreme position C. In which position does the bob have :
(i) maximum potential energy ?
(ii) maximum kinetic energy ?
Give reasons for your answer.

Answer

(i) Maximum potential energy in position C ; Because at position C, the bob is at the maximum height (ii) Maximum kinetic energy in position A ; Because at position A, the bob has maximum speed (or velocity)
