Question

Is rolling friction is smaller than sliding friction. Justify the statement by example an activity for this.​

Answer 1

Answer:

As the area of contact is less in the case of rolling than in the case of sliding, rolling friction is less than the sliding friction. Rolling friction is the resistance to motion experienced by a body when it rolls upon another. It is much less than sliding friction for the same pair of bodies.

Answer 2

Answer:

Yes, rolling friction is smaller than sliding friction

Because in rolling friction, the two surfaces just come in contact, and there is static friction. But in sliding friction, the 2 surfaces rub each other, and causes more friction

For example, it is easier to push heavy goods on logs rather than dragging them along the ground
