Friction force in two books
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 behaves simply. The transition from static friction to kinetic friction is … WebIf the coefficient of static friction is 0.45, you would have to exert a force parallel to the floor greater than. f s (max) = μ s N = ( 0.45) ( 980 N) = 440 N. to move the crate. Once there is motion, friction is less and the coefficient of kinetic friction might …
