Arrange the magnitudes of the following in ascending order : Rolling friction, Sliding friction, Static friction.
Also explain why is that? [3 MARKS]
Answer : 1 Mark
Reason : 2 Marks
Rolling friction ˂ sliding friction ˂ static friction
Rolling friction is least as the points of contacts are very less as compared to other two cases. And we know that limiting friction is more when object is at rest than it is moving.
