Frictional Forces Another quite common force is frictional force. Like the normal force, it is caused by direct contact between surfaces. However, while the normal force is always perpendicular to the surface, the frictional force is always parallel to the surface. To fully describe the cause of friction requires knowledge beyond the scope of classical mechanics. For our purposes, it is enough to know that friction is

These interactions always serve to resist motion, and differ in nature according to whether or not the surfaces are moving relative to each other. We shall examine each of these cases separately....
