WebIn 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 11.6. In the case of slipping, v CM − R ω ≠ 0 v CM − R ω ≠ 0, because point P on the wheel is not at rest on the surface ... WebApr 7, 2024 · The frictional force which is called static friction, comes into force between two static objects, that is the time when the two objects are stationary., whereas kinetic friction comes into force as soon as two objects come into motion. Static friction is variable, whereas kinetic friction is constant. These two statements are the main criteria ...
