The static friction value is the value from zero to the minimum force required to initiate motion. The formula for calculating static friction is:

Static Friction = Normal Force x Static Friction Coefficient.

The maximum or limit of friction between two surfaces is FMAX=μR F MAX = μR. where μ is the coefficient of friction and R is the normal reaction between two surfaces. The coefficient of friction is a measure of surface roughness, with rougher surfaces having higher values. Therefore, as the car makes a circular motion, the necessary centripetal force is provided by the frictional force. Therefore, the coefficient of static friction between a car tire and the road surface is 0.53.
