Friction is the resistance to motion caused by contact between two bodies. If two bodies are in contact, there is not any friction between them unless an attempt is made to move the bodies relative to one another then a friction force develops between them which tends to impede the motion. The impediment to the motion may have two forms: 1. The motion may be completely prevented because the friction force prevents all motion. 2. The bodies may slide relative to one another, but the friction force acts to oppose the motion, even though the friction force is not terse enough to stop the motion.
