Surfaces exert a frictional force that resists sliding motions, and you need to calculate the size of this force as part of many physics problems. The amount of friction mainly depends on the “normal force,” which surfaces exert on the objects sitting on them, as well as the characteristics of the specific surface you’re considering.
