What is potential energy?
Potential energy is stored energy. An apple sitting on the edge of a table has stored potential energy. The potential energy changes to kinetic energy when the apple falls to the ground. A compressed spring has potential energy. That potential energy is converted to kinetic energy when the compressed spring is released.
