Detailed Description

A constant (scalar) "force" f applied to a mobility.

The mobility here selects a generalized speed (u), not a generalized coordinate (q), and the meaning depends on the definition of the generalized speed. If that speed is a translation then this is a force; if a rotation then this is a torque. This force does not contribute to the potential energy, so adding it to a system will cause energy not to be conserved.
