Traction, or tractive force, is the force used to generate motion between a body and a tangential surface, through the use of dry friction, though the use of shear force of the surface is also commonly used.
Friction is a force that opposes motion and wastes energy. Some of the energy used to create the forces that move objects is also used to overcome oppositional forces due to friction. Friction reduces the efficiency of machines and mechanisms, and good designers are always looking for ways to minimize friction.
