The Difference Between Rolling Friction and Sliding Friction

1 Answers

Rolling friction and sliding friction differ in that: the two friction surfaces in sliding friction are fixed, while in rolling friction, one friction surface changes, with the contact points continuously shifting. Rolling friction refers to the friction generated when an object rolls over another object. Sliding friction refers to the frictional force produced when an object slides along the surface of another object. Expansion: 1. Rolling friction is much smaller than both maximum static friction and sliding friction. Generally, rolling friction is only 1/40 to 1/60 of the resistance from sliding friction. Therefore, rolling an object on the ground requires much less effort than pushing it to slide. 2. Sliding friction refers to the frictional force generated when an object slides along the surface of another object. The direction of the sliding friction force acting on the object is opposite to its direction of motion, which is why friction occurs.
