Detailed Description

A force which resists changes in the distance between two points, acting along the line between those points.

The points are specified as a station on each of two bodies. A damping constant c >= 0 is given. If the relative (scalar) velocity between the points is v, then we apply a force of magnitude f=c*|v| to each point in a direction which opposes their separation. This is not a potential force and thus does not contribute to the potential energy calculation. It is an error if the two points become coincident, since we are unable to determine a direction for the force in that case.
