Gravitational Potential Energy Calculator
Estimate the change in gravitational potential energy near Earth’s surface from mass and height relative to a reference.
How to use this calculator
- Enter mass, signed height and the gravitational acceleration suitable for the situation.
- Check the labels and units before using a result outside this page.
- Change one input at a time if you want to compare scenarios.
Formula and method
ΔU = mgh
- ΔU = mgh
- The answer depends on the reference height and assumes a nearly constant gravitational field.
Worked examples
Worked example
A 3 kg object is 2 m above the chosen reference with g = 9.80665 m/s².
ΔU ≈ 3 × 9.80665 × 2 = 58.84 joules.
ΔU ≈ 3 × 9.80665 × 2 = 58.84 joules.
