Laws of rolling friction

Webfriction, force that resists the sliding or rolling of one solid object over another. Frictional forces, such as the traction needed to walk without slipping, may be beneficial, but they also present a great measure of opposition to motion. About 20 percent of the engine power of automobiles is consumed in overcoming frictional forces in the moving parts. WebFirst law: The force of kinetic friction (F k) is directly proportional to the normal reaction (N) between two surfaces in contact. F k ∝ N ∴ F k = μ k N where, μ k = constant called the coefficient of kinetic friction. Second law: Force of kinetic friction is independent of shape and apparent area of the surfaces in contact.
