Experiment has established the following law for sliding friction -both for friction of motion and for friction of rest:

Sliding friction is proportional to the pressure, and independent of the extent of the surfaces in contact. It varies with the character of the surfaces.

Within certain limits friction of motion is also independent of the velocity of the motion.
