Detailed explanation-1: -Rolling friction is the frictional force that occurs when one object rolls on another, like a car’s wheels on the ground. This is classified under static friction because the patch of the tire in contact with the ground, at any point while the tire spins, is stationary relative to the ground.

Detailed explanation-2: -A wheel or ball on a surface is held there by static sliding friction. In order to start the rolling motion, a force or torque must be applied to the wheel. The force of the static sliding friction prevents the wheel from sliding and thus initiates the rolling motion.
