physics-energy conservation

posted by .

when you apply the brakes of a car its kinetic energy or energy of motion decreases.

a)to what form of energy is the kinetic energy converted?
b)where does the resulting energy end up?



Do the brake drums on the wheels heat up?

so does it convert into heat energy?and the resulting energy is used to heat the brake drums up?

(b) Eventually, the car's kinetic energy is transfered as heat from the brakes to the environment, as the brakes cool down again.
