Question

why rolling friction is so small​

Answer 1

hey mate!

Rolling resistance is usually less than static friction because the surface of contact is very very small in real life so the net normal force is also small and not enough like the static friction to prevent the body from sliding and keep it unmoved and static friction also increases with the increase of the external
