Chapter 50, Problem 4RQ
When the brakes are applied on a moving car, the frictional parts (brake or) are forced against the rotating parts of the car (brake or). The friction causes the rotating parts to slow down and stop. Just as the energy of the rotating parts is called kinetic, the friction used to stop them is called kinetic.
