The control engineer often assumes a viscous friction model. To describe dry rubbing the tribologist rarely includes any velocity dependence at all, and when he does it is as likely to be negative as positive. Based on the experimental work presented here, the kinetic plus viscous friction model seems very accurate at velocities above a minimum velocity. Below the this velocity, decreasing friction with increasing velocity, or negative viscous friction, is observed.
