What is the Potential Energy Calculator?
Calculate gravitational potential energy from mass and height.
Enter mass, height and gravity and the Potential Energy Calculator returns potential energy and speed if dropped from that height. Results update as you type, and nothing you enter leaves your device.
How it is calculated
PE = m × g × h
How to use it
- Enter mass in kg.
- Enter height in m.
- Enter gravity in m/s².
- Read potential energy in the results panel. It updates as you type.
- Change any value to compare scenarios, or use Share to send the result as a link.

Common questions
What formula does the Potential Energy Calculator use?
It uses: PE = m × g × h.
What do I need to use the Potential Energy Calculator?
You need mass, height and gravity. Sensible starting values are filled in so you can see how it works straight away.
Is the Potential Energy Calculator free, and is my data stored?
It is free with no sign-up. The calculation runs in your browser, so the values you enter are not sent to or stored on our server.
