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 · Calculating friction is a key part of classical physics, and rolling friction addresses the force that opposes rolling motion based on the characteristics of the surface and the rolling object. The equation is similar to other friction equations, except with the coefficient of rolling friction.
Rolling resistance, sometimes called rolling friction or rolling drag, is the force resisting the motion when a body (such as a ball, tire, or wheel) rolls on a surface. It is mainly caused by non-elastic effects; that is, not all the energy needed for deformation (or movement) of the wheel, roadbed, etc., is recovered when the pressure is removed.
For a rolling motion of a wheel, we demand that the wheel does not slide on the surface. The “non-sliding” condition means that the small part of the wheel that is in momentary contact with the surface must be static by a static friction. This static friction is called the rolling friction.
