Friction

  • Chapter
Physics

Abstract

Numerous references have already been made to frictional effects, because friction is present in almost every practical problem in mechanics. Friction is needed to make most methods of propulsion on the surface of the earth possible — cars and trains would not move, nor could one walk, if the surface were frictionless. On the other hand, whenever one surface slides or rolls over another, friction causes a loss of mechanical energy and the production of heat, both of which may be undesirable.
