Web12 sep. 2024 · In the case of rolling motion with slipping, we must use the coefficient of kinetic friction, which gives rise to the kinetic friction force since static friction is not present. The situation is shown in Figure 11.2. 5. In the case of slipping, v CM − R ω ≠ 0, because point P on the wheel is not at rest on the surface, and v P ≠ 0.
