Question:

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.

(a) Rolling, static, sliding
(b) Rolling, sliding, static
(c) Static, sliding, rolling
(d) Sliding, static, rolling

Answer:

(c) Static, sliding, rolling

Static > sliding > rolling

Because in rolling the interlocking time between two surfaces are very less as compared to the sliding and static friction. In static friction, the interlocking time between two surfaces are greater. So, static friction is higher than sliding and rolling friction. The area of contact is very less in rolling friction as compare to static and sliding friction.
