Kinetic and potential energy
Kinetic and potential energy: formula, units and explained result. No account required. Processing stays in your browser.
Ec = ½mv²; Ep = mgh; E = Ec + Ep
Gravitational potential near the surface. Does not include losses.
How to use this calculator
- Identify the quantities and convert them to the units shown.
- Apply the formula first, then compare with the substitution and result.
- Check the assumptions and whether the order of magnitude makes sense.
Levels are approximate topic groupings, not a complete curriculum for every country. Numerical results are rounded and may lose precision for extreme or nearly singular inputs.
