What happens to the energy in the pendulum as it swings from point A to point B? A. potential energy

B. kinetic Energy

C. kinetic Energy is converted to chemical energy

D. Chemichal energy is converted to themal energy​

The potential energy stored when the weighted end of the pendulum is paused at one point, it is converted to kinetic once in motion, so when going from one point to the other it becomes kinetic.

Explanation:

B kinetic energy or C kinetic energy is converted to chemical energy *but i am not sure*
