Arrange the following in increasing order of their magnitude.
Rolling friction and sliding friction

Is static friction less or greater than rolling friction?

Four children were asked to arrange forces due to rolling, static and sliding frictions in a decreasing order. Write in proper order.

It is easier to roll an object than to slide it.

Rolling friction is much less than the _____ friction. (Sliding/ force of friction)

Sliding friction is _____ than static friction.(less/more)

Suppose your writing desk is tilted a little. A book kept on it starts sliding down. Show the direction of the frictional force acting on it.

Define the term rolling friction.

Define the term sliding friction.

Define the term static friction.

Explain why, sliding friction is less than static friction.
