It is related to the roughness of the surface and has nothing to do with the size of the contact area. According to the nature of motion, it can be divided into dynamic friction coefficient and static friction coefficient. The sliding frictional force is generated when two objects are in contact and slide relative to each other. When the road is in use, it is necessary to detect the anti-slip force and friction coefficient of the road, and generally a pendulum friction coefficient tester is used for detection.
