Question

Four children were asked to arrange friction due to rolling, static and sliding 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 1

Answer: (C)

Static, Sliding, Rolling

As we all know static friction is always greater than kinetic friction. Rolling friction similar to the static friction it depends on the load apply, and its value is veritable, but in practical Rolling friction is less than the Static Sliding Friction.

Hence:

Static > Sliding > Rolling
