The Law of Conservation of Energy states that energy cannot be created or destroyed but can be changed from one form to another. When you release a toy car, you notice that it slows down and eventually comes to a stop but the wheels are slightly warm to the touch. Explain how the law of conservation of energy is obeyed in this scenario.
