Potential Energy Calculator
Find gravitational potential energy with PE = m·g·h.
Energy stored by height
Gravitational potential energy is the energy an object gains simply by being raised. Drop it and that stored energy converts into motion — the basis of hydroelectric dams and roller coasters alike.
A 10 kg mass lifted 5 metres on Earth stores about 491 joules. Change the gravity value to model the Moon or Mars and see how the same lift stores far less energy.

Frequently Asked Questions
What is potential energy?
The energy stored in an object because of its height in a gravitational field. Lift something higher and it stores more.
What is g?
The gravitational acceleration, about 9.81 metres per second squared on Earth. You can change it for other planets.
What units are used?
Mass in kilograms, height in metres, and gravity in metres per second squared give energy in joules.
