What is potential energy?

Gravitational potential energy is energy stored due to height: PE = mgh. A ball at the top of a ramp has high PE; it converts to kinetic energy as it rolls down.

How is potential energy different from kinetic energy?

Potential energy is stored energy (position). Kinetic energy is energy of motion. Total mechanical energy = PE + KE, which is conserved in ideal systems.

Potential Energy Calculator

Quick answer: Enter mass (kg) and height (m) to calculate gravitational potential energy in joules.

Calculate gravitational potential energy (PE = mgh) from an object's mass and height above a reference point. This is the energy stored by virtue of position in a gravitational field.
