Why Rolling Friction Is Less Than Sliding at Marsha Paris blog

Why Rolling Friction Is Less Than Sliding. If the object’s center of rotation moves faster than vr, the rotation can’t ‘keep up’, and the object slides over the surface. You may ask why a rolling object that is not slipping conserves energy, since the static friction force is nonconservative. The force resisting the motion of a rolling body on a surface is known as rolling friction. Rolling friction is potentially greater than sliding friction all else equal, because rolling friction uses the static coefficient, while sliding uses the kinetic coefficient, and the static coefficient can be higher. Rolling friction allows for smooth movement, generates less heat, provides better traction and stability, and reduces wear and damage. Rolling of bike wheels and car tires are the examples of rolling friction. We call this type of motion slipping. Rolling friction is less than sliding friction because when an object rolls, only a small part of the object is in contact with the surface at any given time. The friction depends on the load, diameter of the rolling object, and surface area of the object. If the sliding friction is lower than rolling friction, the object just won't roll unless it has another source of energy, like a motor. The answer can be found by referring back to figure \(\pageindex{2}\).
