why does applying the brakes of a car cause the temperature of the breaks to increase?
The increase in heat is caused by friction between the brakes and the wheels. This work done between the brakes and the wheels, causes a decrease in kinetic energy in the wheels, resulting in an increase in thermal energy in the brakes.
