# Definition:Potential Energy

## Definition

Let $B$ be a body.

The potential energy of $B$ is the energy appertaining to $B$ as a result of its position in a force field or because of the internal configuration of its components.

## Examples

### $1 \ \mathrm N$ raised $1 \ \mathrm m$

A body which requires $1$ newton to hold it against the force of gravity when raised through a distance of $1$ metre has $1$ joule of potential energy transferred to it.
