Formula to calculate friction force
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. 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 ...
