Final answer:
Brake shoes exert pressure on the brake drum to stop a car. Friction between the shoes and the drum converts the car's kinetic energy into heat energy, resulting in the car stopping.
Step-by-step explanation:
The brake shoes on a car exert pressure on the brake drum to stop the car. When the driver presses the brake pedal, a system of hydraulic brakes is activated, which increases the force applied to the brake shoes. The force applied to the brake shoes creates friction between the shoes and the brake drum, resulting in the car coming to a stop.
Friction is also involved in the process, as the brake shoes rubbing against the brake drum convert the car's kinetic energy into heat energy, ultimately causing the car to stop.
