That values of μ μ in Table 5.1 are stated to only one or, at most, two digits is an indication of the approximate description of friction given by the above two equations. The friction force is the force exerted by a surface when an object moves across it - or makes an effort to move across it. The frictional force can be expressed as. Ff = μ N (1) where. Ff = frictional force (N, lb) μ = static (μs) or kinetic (μk) frictional coefficient. N = normal force between the surfaces (N, lb) The coefficient of static friction is a dimensionless quantity that represents the maximum amount of friction force that can exist between two surfaces without causing movement. In the case of a ladder and a friction-less wall, the coefficient of static friction would be zero since there is no friction force present. 2.
