Coefficient of friction

Friction Coefficient (of frictional interaction) expresses the quantitative application of force sufficient to ensure sliding (motion) of one physical body on the surface of another.

The weight multiplied by the static friction coefficient results in the friction force value - F = mN, the value of which is sufficient to start the motion. To find out the value of the force supporting the motion, the kinetic friction coefficient needs to be used in the formula.

Using the calculation of the coefficient value and friction force can be applied in many practical studies. It's no wonder that in physics there is a section of the mechanics of friction (tribology). This is important for shipbuilding, including the design of submarines.
