Detailed Description

A constant force f (a signed scalar) which acts along the line between two points, specified as a station on each of two bodies.

A positive force acts to separate the points; negative pulls them together. The force magnitude is independent of the separation between the points. This force does not contribute to the potential energy, so adding it to a system will cause energy not to be conserved. It is an error if the two points become coincident, since we are unable to determine a direction for the force in that case.
