Joule

(SI unit of energy)

The Joule is an SI (derived) unit of energy equivalent to the work done by the force of a Newton (a unit of force) pushing over a meter distance. A Joule is one kilogram meter-squared per second-squared (kg·m²/s²), a Newton being the force necessary to accelerate a kilogram by one meter per second-squared. A Joule is also a Watt-second. 107 Ergs make a Joule.
