Question

Answer the following in short.

Define rolling friction and give an example where rolling. friction comes into play.

Answer 1

When we roll an object on a surface, the friction produced between the object and the surface is called rolling friction. Example: when we pull our large suitcases on wheels, rolling friction comes into play. The wheels reduce friction and cut down a lot of effort required to move the suitcase (Rolling friction is less than sliding friction).
