摘要

If the motion of a body along a rough surface is modelled such that the point of contact has a zero velocity, in many cases qualitatively incorrect results can be obtained. For the model to be physically valid, it is necessary to take into account the finite contact area and the presence of rotational friction, along with the sliding friction.
