The force resisting the motion of a rolling body on a surface is known as rolling friction. The friction depends on the load, diameter of the rolling object, and surface area of the object. Rolling of bike wheels and car tires are the examples of rolling friction.

3 Φεβ 2023 · What is Rolling Friction. When an object rolls over the surface, it experiences resistance to its motion. This resistive force is a type of kinetic friction and known as rolling friction. The point at which the object is in contact with the surface is critical in understanding rolling friction.
22 Δεκ 2020 · Rolling friction is a type of kinetic friction, also known as rolling resistance , which applies to rolling motion (as opposed to sliding motion – the other type of kinetic friction) and opposes the rolling motion in essentially the same way as other forms of friction force.

rolling friction, type of friction that occurs when a wheel, ball, or cylinder rolls freely over a surface, as in ball and roller bearings. In general, friction is the force that resists the sliding or rolling of one solid object over another.
Examples where energy is not conserved are a rolling object that is slipping, production of heat as a result of kinetic friction, and a rolling object encountering air resistance. You may ask why a rolling object that is not slipping conserves energy, since the static friction force is nonconservative.
If a wheel rolls along the ground without slipping, there is a rolling frictional force at the point of contact between the wheel and the ground, due to the forming of chemical bonds between the wheel and the ground at that point, and the breaking of those bonds as the wheel moves along to the next point.
