Potential Energy Calculator

Calculate the gravitational potential energy of an object based on its mass and height. This is the energy stored due to position.

PE = m × g × h

Where PE is potential energy in Joules, m is mass in kg, g is gravity (9.81 m/s² on Earth), and h is height in meters.

What is the reference point for height?

Height is measured from your chosen reference point (usually ground level). PE is relative - only changes in height matter for energy calculations.

How does gravity vary?

Earth: 9.81 m/s², Moon: 1.62 m/s², Mars: 3.71 m/s². Use different values for other planets.
