Four children were asked to arrange forces due to rolling, static and sliding frictions in a decreasing order. Their arrangements are given below. Choose the correct arrangement. [1 mark]

(a) rolling, static, sliding
(b) rolling, static, sliding
(c) static, sliding, rolling
(d) sliding, static, rolling

Solution

Option (c). static, sliding, rolling (1 mark)

Sliding friction is less than the maximum static friction that can act between two surfaces in contact. As the contact surfaces don't get enough time to interlock properly while rolling, rolling friction is the least out of the three types of friction.
