Definition:Potential Energy

Definition

Let $B$ be a body.

The potential energy of $B$ is the work done by a conservative force in bringing $B$ from a given point to some standard reference point.

Examples

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

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

Historical Note

The concept of potential energy was first introduced by Joseph Louis Lagrange.
