Formula of force of friction

WebOnce an object is moving, the magnitude of kinetic friction fk is given by f k = μ k N. where μ k is the coefficient of kinetic friction. Friction varies from surface to surface because different substances are rougher than others. Table 5.2 compares values of static and kinetic friction for different surfaces. WebMar 26, 2016 · This equation tells you that when you have the normal force, FN, all you have to do is multiply it by a constant to get the friction force, FF. This constant, is called the coefficient of friction, and it’s something you measure for contact between two particular surfaces. ( Note: Coefficients are simply numbers; they don’t have units.)
