WebCoe˝cient of (sliding) friction is a unit-less number that describes the ratio of the force of friction between two bodies and the force pressing them together. The coe˝cient of (sliding) friction depends on the materials used; for example, steel on ice has a low coe˝cient of friction, while rubber on pavement has a high coe˝cient of friction. Web5.1 Friction. 5.1 Friction. Highlights. Friction is a force that is around us all the time that opposes relative motion between surfaces in contact but also allows us to move (which you have discovered if you have ever tried to walk on ice). While a common force, the behavior of friction is actually very complicated and is still not completely ...
