WebStatic friction is the frictional force that exists between two solid surfaces, that are non-moving. The lateral relative motion between these two surfaces, is stalled by the force of static friction. Due to it, there is no slipping and … WebAs with the static frictional force, the kinetic frictional force acts to oppose the relative motion of the surfaces in contact. One important difference between the two is that the kinetic friction equation has an equals sign: the kinetic force of friction is always equal to the kinetic coefficient of friction times the normal force.
