Rollen met uitglijden

In rolling without slipping, the linear velocity of the center of mass of an object is equal to the object's radius multiplied by its angular velocity. The point in contact with the surface has zero velocity.

When the object rotates faster, the point in contact with the surface experiences rolling with backward slipping.

Here, the center of mass of the object covers a shorter distance than when rolling without slipping.

In this motion, the kinetic friction works opposite to the backward slipping, and tries to minimize the angular velocity.

However, if the object rotates slowly, then the point in contact with the surface experiences rolling with forward slipping.

Here, the center of mass of the object covers a longer distance than when rolling without slipping.

In this motion, the kinetic friction acts opposite to the forward movement of the object and tries to maximize the angular velocity.

For forward slipping motion, the extreme situation occurs when the angular velocity becomes zero and the object undergoes pure translational motion.
