When the toy car is pulled back, it gains potential energy. When it is released, the potential energy is converted into kinetic energy, which causes the car to move.
Electrical Energy to Kinetic Energy
Some toy cars are powered by batteries. When the batteries are connected to the motor, the electrical energy is converted into kinetic energy, which causes the car to move.
Heat Energy to Kinetic Energy
Some toy cars are powered by gas. When the gas burns, it produces heat energy. The heat energy is converted into kinetic energy, which causes the car to move.
