Quick answer

Work is force times distance in the direction of motion; power is work divided by time.

W = Fd cos θ, P = W/t

How to use the Work and Energy Calculator

  1. 1Enter the applied force in newtons.
  2. 2Enter the distance moved in metres.
  3. 3Add the angle between force and motion if not aligned.

Frequently asked questions

Why does a 90° angle give zero work?

A perpendicular force does not move the object along its direction of travel.

Is work the same as energy?

Work is energy transferred by a force — same units, joules.
