Answer:
<em>When a moving car brakes to a stop the </em><em>kinetic energy of the car is converted to heat energy. </em>
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.
