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.


The displacement of the bob in a simple pendulum is as shown in the figure below:


 From the above figure, we can conclude that:

(i). At extreme positions B and C, the bob has maximum potential energy.

(ii). At center position A, the bob has maximum kinetic energy.
