How to use the gravitational potential energy calculator
Find gravitational potential energy from mass, height and gravity. Enter mass, height, gravity in the fields above; the potential energy, potential energy are computed instantly and plotted on the chart so you can see how the answer changes.
Formula
Variables
- m — Mass (kg)
- h — Height (m)
- gr — Gravity (m/s²)
Worked example
With mass = 5 kg, height = 10 m, gravity = 9.80665 m/s², the calculator gives potential energy ≈ 490.3325 J; potential energy ≈ 0.4903325 kJ.
Frequently asked questions
What is the formula for the gravitational potential energy calculation?
Potential energy (J) = m × gr × h. Potential energy (kJ) = [Potential energy] / 1000. Here m is mass (kg), h is height (m), gr is gravity (m/s²).
What inputs do I need for the gravitational potential energy calculator?
You need mass in kg, height in m, gravity in m/s². Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use this calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
