The ability to do work.
A force applied over a distance. For formulae, see work done by a constant force parallel to displacement and work done by any constant force, and work done by a position-dependent force.
The units of work, equivalent to a Newton-meter. Also units of energy.
The energy of motion.
Work done per unit time. For formulas, see Formula for average power, Definition of instantaneous power, and formula for instantaneous power.
Unit of power; equal to joule/second.
| Work done by a constant force parallel to displacement | W = Fx |
| Work done by any constant force | W = Fx cosθ |
| Work-Energy Theorem | W = ΔK |
| Formula for average power |  =  |
| Definition of instantaneous power | P =  |
| Formula for instantaneous power | P = Fv cosθ |
| Work done by a position-dependent force | W =  F(x)dx force.
