Question

An illustration of a girl sitting on a swing from the end. The height the swing is above the ground at the equilibrium position is labeled A. A second position is where she swings forward and the swing is now a distance B above the ground.
At which position, A or B, is the potential energy of the swing the greatest?


As the swing moves from point B to point A, which form of energy is increasing, kinetic or potential?

Answer 1

Potential energy is greatest at B (higher height).

As the swing moves from B down to A, kinetic energy increases (gravitational potential energy is converted into kinetic energy).
