Potential Energy is energy due to position. Systems or objects with potential energy are able to exert forces (exchange energy) as they change to other arrangements.
Gravitational potential energy describes the energy of an elevated object. The term is often shortened to just "potential energy" in physics because the most common type of potential energy in physics problems is gravitational. Unless otherwise stated, you can assume "potential energy" means gravitational potential energy.The equation used to calculate an object's the potential energy is listed at right:
