coefficient of kinetic friction

coefficient of kinetic friction

[¦kō·ə′fish·ənt əv kə′ned·ik ′frik·shən]
(mechanics)
The ratio of the frictional force, parallel to the surface of contact, that opposes the motion of a body which is sliding or rolling over another, to the force, normal to the surface of contact, with which the bodies press against each other.

After slip, the coefficient of static friction changes to the coefficient of kinetic friction. Including viscous effects dictates the use of Newton's law of viscosity as well.
Since the coefficient of kinetic friction is smaller than the coefficient of static friction, the torque resulting from dry friction after slip is lower than that required to start slip.
