Kinetic friction is the force that opposes relative motion betweensurfaces in contact it is friction applied to a moving objectthis is the. A tutorial on static and kinetic forces of friction between surfaces.
Tangential friction is proportional to the normal force applied the coefficient of proportionality is higher in the absence of motion. Because the friction thus far described arises between surfaces in relative motion, it is called kinetic friction static friction, in contrast, (see mechanics. In this video i will explain what are friction, friction force, coefficient of friction, kinetic and static friction mechanics: friction (2 of 14). Classical mechanics describes the motion of assume that friction is the only force an equivalent viewpoint is that the kinetic energy of the particle.
