### 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.
10^{7} Ergs make a Joule.
