Friction and frictional heat generation

This normal force leads to a friction force Ff which equals


\begin{displaymath}
F_f = \nu \: F_n
\end{displaymath}

where $\nu$ is the friction coefficient (see contact_friction. The friction force causes heat generation rate Q:


\begin{displaymath}
Q = \eta \: F_f \: v_f
\end{displaymath}

where vf is the slip velocity, and the factor $\eta$ is a user specified factor which determines which part of the frictional energy loss is transformed into heat ($\eta$ is between 0 and 1; see contact_heat_generation).
