... Friction is a force that resists, or works against, motion. It slows down moving objects and creates heat. Try rubbing your hands together; you will feel them getting warmer and warmer. Friction occurs because no surface is perfectly smooth. Even surfaces that look smooth to the unaided eye appear r ...

... This form for the frictional force is an approximation; the actual phenomenon is very complicated. The coefficient of friction may vary somewhat with speed; there may be some dependence on the surface area of the objects. Also, remember that these equations are for the magnitude of the frictional fo ...
