How It Works
How It Works
This calculator finds the gravitational potential energy of an object. Potential energy is the stored energy an object has because of its height above the ground.
It uses the formula PE = mass × gravity × height. You enter the object's mass (in kilograms), the height (in meters), and optionally the gravity value. If you don’t enter gravity, it uses 9.8 m/s², which is the standard gravity on Earth.
- Mass is how heavy the object is (in kilograms).
- Height is how high the object is above the ground (in meters).
- Gravity is the strength of gravity (9.8 m/s² on Earth by default).
- Multiply all three values to get potential energy in joules (J).
Understanding the Results
The result shows how much stored energy the object has because of its position. The higher or heavier the object, the more potential energy it has.
If you increase the mass or the height, the potential energy increases. If either mass or height is zero, the potential energy will also be zero.
- The result is measured in joules (J).
- A larger mass gives more potential energy.
- A greater height gives more potential energy.
- Zero height means zero potential energy.
Frequently Asked Questions
What is potential energy?
PE is stored energy due to position in a gravitational field. PE = mgh.
What is g?
g is gravitational acceleration. On Earth: 9.8 m/s². On Moon: 1.62 m/s².
PE and KE relationship?
When falling, PE converts to KE. Total mechanical energy (PE+KE) is conserved.
