... For the same weight, rolling friction is much smaller (even by 2 or 3 orders of magnitude) than static or sliding friction. Q. List some of the disadvantages of friction and remedy. A. Machine with different moving parts, friction does have a negative role. It opposes relative motion and thereby dis ...
