i am not exactly sure but i think there is
a mouse toy
a cheese toy, another mouse toy, etc
at the top of the ramp the toy has a certain amount of potential energy. The amount of this energy depends on the height of the ramp and the weight of the toy. (The toy's weight is dependent on its mass and the force of gravity.) As the toy rolls down the ramp this potential energy is converted to two other types of energy: Kinetic energy and heat energy. The amount of heat energy depends on friction and air resistance. The lower the total resistance the more kinetic energy, and the more speed, the toy has at the bottom of the ramp.
When a wind-up toy is released, the energy stored in the compressed spring is converted into kinetic energy, causing the toy to move. This movement occurs as the spring unwinds and transfers its stored energy into the toy's mechanical components.

In a wind-up toy, mechanical energy is generated when the toy is wound up, but some of this energy is wasted as heat due to friction in the gears and moving parts. Additionally, sound energy is produced as the toy operates, which can also be considered a form of energy loss. Overall, the efficiency of the energy transfer from the winding mechanism to the toy's movement is not 100%, leading to energy wastage in various forms.
In a wind-up toy, energy is wasted as a result of friction in the moving parts and air resistance. The amount of energy wasted can vary depending on the design and efficiency of the toy, but typically a significant portion of the energy put into winding up the toy is lost as heat and sound rather than being used to move the toy.
Kinetic energy is used to overcome friction and is dispersed as heat; some energy is converted to sound.
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.
It depends on the type of toy car. In a simple wind-up version, mechanical energy, of a spring under tension, is converted to kinetic energy and noise and a small amount of heat. In battery powered cars, chemical energy from the batteries is converted to electricity which in turn is converted to kinetic energy and waste.
You use a match or lighter to heat up the plastic. Do not touch the plastic with the flame though. Hold it about a centimeter below the plastic.
