Work is said to be done by a force when it moves its point of application through a distance.

Work done = Force × Distance moved

SI unit of work is joule. 1 J = 1 N.m

Joule: When a force of 1 Newton acting on a body through a distance of 1m

Power is defined as the rate of doing work.

P = W/t (J/s = Watt)

Joule = Watt × second
