Friction physics

WebThe friction force is calculated by multiplying the reaction of the surface N and the coefficient of friction k. The formula of the friction force will have the following form: F fr = k * N. In some formulas, the coefficient of friction k is denoted by the symbol µ. The above calculations are valid in the simplest case when the body lies on a ...
