WebThe magnitude of kinetic friction fk is given by. fk = μkN, 6.2. where μk is the coefficient of kinetic friction. A system in which fk = μkN is described as a system in which friction … WebFriction is a force that acts to stop the movement of two touching things. The energy lost to friction is turned into sound and heat. Two kinds of friction are static and kinetic. Static friction is when the friction is strong enough to stop movement between two objects. Kinetic friction is used when the frictional force is not strong enough to ...
