WebOnce there is motion, friction is less and the coefficient of kinetic friction might be 0.30, so that a force of only 290 N (f k = μ k N = 0. 30 980 N = 290 N f k = μ k N = 0. 30 980 N = 290 N) would keep it moving at a constant speed. If the floor is lubricated, both coefficients are considerably less than they would be without lubrication. WebA simple, as well as an effective model for friction, is that the force of friction, f, is equal to the product of the normal force, N, and a number called the coefficient of friction, μ. It …
