A wind-up toy car primarily contains mechanical energy and potential energy. When the toy is wound up, the energy is stored as potential energy in the tension of the spring. As the spring unwinds, this potential energy is converted into mechanical energy, which powers the movement of the car. Additionally, some energy is transformed into thermal energy due to friction as the car moves.
A windup toy typically uses a combination of a wheel and axle for movement, gears for transferring rotational motion, and a spring for storing potential energy that is released as the toy walks or moves. These components make it a complex machine rather than a simple one.
When a wind-up toy is released, the potential energy stored in the compressed spring is converted into kinetic energy, causing the toy's moving parts to start moving as the spring unwinds. This kinetic energy drives the motion of the toy until the energy in the spring is fully depleted.
Mechanical energy is not produced in a toy car. Instead, the toy car converts potential energy (stored energy) into kinetic energy (energy of motion) as it moves. The mechanical energy in the toy car comes from the energy used to make it move, not from being produced within the toy itself.
In a wind-up toy, mechanical energy is converted to potential energy when the spring is wound up. When the toy is released, the potential energy is converted back into mechanical energy as the spring unwinds, causing the toy to move. This movement can also create sound energy and some heat due to friction.

The magnitude of the displacement of the windup toy is zero. Since it starts and ends at the same position, the net change in position is zero, resulting in zero displacement.

Chemical Energy to Mechanical Energy
You can power a toy car by using batteries or rechargeable battery packs. The batteries supply electrical energy to the electric motor in the toy car, which then converts the energy into motion to make the car move.
