Question

why rolling friction is much smaller than static and kinetic friction​

Answer 1

Answer:

Rolling friction is always less than static friction because in order for an object to roll the force of friction between it and surface must be large enough to keep the object from sliding. Hence rolling friction is always greater than static force.
