Did you know?
WebThe coefficient of friction is the ratio between the force slowing something down and the force pushing them together. The larger it is the stronger friction is (and the more the object is slowed down). For example, a person's skates on ice have a small coefficient of friction, but rubber on concrete has a big one.
