Acar in motion has kinetic energy. what happens to the kinetic energy when the car brakes to a stop? the kinetic energy is transformed into potential energy ready to be released when the car starts back up. the kinetic energy is lost since energy is not conserved. the kinetic energy is transformed into heat energy evident by the warmth of the tires and is dissipated. the kinetic energy is still there, it is just not observable.

When a moving car brakes to a stop the kinetic energy of the car is converted to heat energy.

Explanation:

A moving car has kinetic energy.

It is given by the equation

Where m denotes mass of the car and v denote sits velocity. When the brakes are applied the velocity becomes zero and the car doesn’t possess kinetic energy anymore.

According to law of conservation of energy can neither be created nor be destroyed but can only be transformed from one form to another. On coming to a stop,  the kinetic energy of the car  gets converted to heat. The friction between the tyre and the road heats up the tyre.
