WebThis 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.)
