About the Work, Power & Energy Calculator
A work, kinetic energy, potential energy, and power calculator, in your browser.
What it is
The Work, Power & Energy Calculator covers four core mechanics formulas: work (W = Fd cosฮธ), kinetic energy (KE = ยฝmvยฒ), gravitational potential energy (PE = mgh), and power (P = W/t). Switch between modes to solve whichever calculation you need, with the formula and substitution shown for every result.
Features
Four calculators in one
Work, kinetic energy, potential energy, and power, without switching tools.
Angle-aware work formula
Accounts for the angle between force and displacement, not just straight-line cases.
Adjustable gravity
Defaults to Earth's 9.81 m/sยฒ, but accepts any value for other worlds.
Step-by-step working
See the exact formula and substitution used to reach every result.
