Question

Rolling friction is about -------------- times lesser than the sliding friction

Solution

Hi Aish!

Rolling friction is always very much less than sliding friction. The rolling friction of steel on steel is 1/100 times less than the sliding friction of steel on steel. That is, the ratio depends on the materials in contact.
