What is the Potential Energy Calculator?
Calculate gravitational potential energy from mass and height. These physics and science calculators apply standard SI formulas with exact constants (such as g = 9.80665 m/s² and the 2019 SI definitions) for students, engineers and curious minds.
How to use the Potential Energy Calculator
- Enter your mass, your height, your gravity.
- Results update automatically as you type; you can also press Calculate.
- Read the output: potential energy, impact speed if dropped.
- Use the 📊 chart to see the result visually, then copy or share it.
Formula and method
Worked example
With mass = 50 kg, height = 10 m, gravity = 9.80665 m/s², the Potential Energy Calculator returns potential energy: 4,903.33 J; impact speed if dropped: 14.005 m/s.
Tips for better results
- Convert inputs into SI units first for the cleanest results.
- Idealized formulas ignore friction and air resistance unless stated.
- Use our unit converters to switch between metric and imperial results.
