How does potential energy change in a pendulum?

Back

In a pendulum, potential energy is highest at the highest points of the swing and lowest at the lowest point.

What is the principle of conservation of mechanical energy?

Back

The principle states that in the absence of non-conservative forces (like friction), the total mechanical energy of a system remains constant.
