# Gravitational Potential

In classical mechanics, the gravitational potential at a location is equal to the work (energy transferred) per unit mass that is done by the force of gravity to move an object to a fixed reference location. It is analogous to the electric potential with mass playing the role of charge. By convention, the reference location is usually taken at infinity, so the gravitational potential is zero infinitely far away from any mass and negative at any finite distance.

In mathematics the gravitational potential is also known as the Newtonian potential and is fundamental in the study of potential theory.

### Famous quotes containing the word potential:

Views of women, on one side, as inwardly directed toward home and family and notions of men, on the other, as outwardly striving toward fame and fortune have resounded throughout literature and in the texts of history, biology, and psychology until they seem uncontestable. Such dichotomous views defy the complexities of individuals and stifle the potential for people to reveal different dimensions of themselves in various settings.
