Potential Energy of Position

Physical Law
Let $B$ be a body of mass $m$ in a gravitational field.

Let the Acceleration Due to Gravity be of constant magnitude $g$.

Let $B$ be at a height $h$ above a reference level $h_0$.

Then the potential energy $P$ of $B$ due to the position of $B$ relative to $h_0$ is given by:
 * $P = m g h$
