Answer 2

Rolling friction is always less than sliding friction

Explanation:

• Rolling friction is less than the sliding friction because, the area of contact is smaller in rolling friction than in sliding friction.
• The frictional force acting on an object when it slides over a surface is sliding friction. Eg: Sliding a box on the floor
• The frictional force experienced by an object, when it rolls over a surface is rolling friction. Eg: Trolley bags, Wheels etc.
