About this calculator
Gravitational potential energy is the energy stored by lifting an object, PE = m × g × h, in joules. The default gravity is Earth’s standard 9.80665 m/s², which you can change under advanced options for other planets or the Moon.
Frequently asked questions
What is gravitational potential energy?
It is the energy an object gains by being raised against gravity, PE = m × g × h. A 2 kg mass lifted 10 m on Earth stores 2 × 9.80665 × 10 ≈ 196 joules.
Does potential energy depend on the reference height?
Yes. PE is measured relative to a chosen zero level, usually the ground. Only differences in height between two points are physically meaningful.
