Work, Energy and Power Calculator
Find the work done by a force, the power of a machine and how efficient it is. Every formula can be rearranged, and you can work with forces at an angle.
What you can do
- Work done, force or distance from W = Fd
- Work with the force at an angle
- Power, energy or time from P = E/t
- Power from force and speed
- Efficiency, useful output or total input, with wasted energy shown
- Units including kJ, kW, horsepower and hours
