WebbSliding friction forces can be calculated from knowledge of the coefficient of friction and the normal force exerted upon the object by the surface it is sliding across. The formula is: F frict-sliding = μ frict-sliding • F norm. The symbol μ frict-sliding represents the coefficient of sliding friction between the two surfaces.
