The kinetic energy store of the car has been transferred to the thermal energy store in the brakes increasing the brakes temperature. Tension acts between the car and the wheels. The thermal energy store of the car has been transferred to the kinetic energy store in the brakes increasing the brakes temperature. Gravity acts between the brakes and the wheels. The gravitational energy store of the car has been transferred to the thermal energy store in the brakes decreasing the brakes temperature.	23810	51	43	466.8627450980392	466.86	Incorrect	tre	1/1
