Energy It is equal to the energy expended (or work done) in applying a force of one newton through a distance of one metre.

The SI unit of energy rate (energy per unit time) is the watt, which is a joule per second. Thus, one joule is one watt-second, and 3600 joules equal one watt-hour. The CGS energy unit is the erg and the imperial and US
