A racecar driver drives on a straight track (with friction). He pushes on the brake and the car slows down. What is happening to the kinetic energy of the car as he applies the brake.
The kinetic energy disappears
The kinetic energy is converted into chemical potential energy
The kinetic energy is converted into thermal energy
The kinetic energy stays constant
