How It Works

Gravitational Potential Energy

Potential energy represents stored energy due to an object's position in a gravitational field.

Formula

PE = m * g * h

where m is mass, g is gravitational acceleration, and h is height above a reference point.

Worked Example

A 10 kg object is raised 20 meters above the ground.

mass = 10gravity = 9.81height = 20
  1. 01PE = m * g * h
  2. 02PE = 10 * 9.81 * 20
  3. 03PE = 1962 J
  4. 04PE = 1.962 kJ
