Types Of Friction - Static, Sliding, Rolling And Fluid Friction

When an object is rolling without slipping, the rolling friction force is much less than the friction force when the object is sliding; a silver dollar will roll on its edge much farther than it will slide on its flat side (see Section 5.3). When an object is rolling without slipping on a horizontal surface, we can approximate the friction force to be zero, so that ax and az are approximately zero and vx and are approximately constant. Rolling without slipping means vx = rand ax = r. If an objec
