It is due to its smooth surface, with an assist from specialized fluids, that bones can meet and glide, almost frictionless, against one another. The key word here is “almost.”. Over time, wear and tear do take a toll. WebFriction arises in part because of the roughness of the surfaces in contact, as seen in the expanded view. In order for the object to move, it must rise to where the peaks can skip along the bottom surface. Thus a force is required just to set the object in motion. Some of the peaks will be broken off, also requiring a force to maintain motion. tollwood winter münchen 2022
