The main transformation of energy in this example is from the chemical energy in Jay's body to kinetic energy in the car.
What is Energy?
Energy is the capacity for doing work. It may exist in potential, kinetic, thermal, chemical, nuclear, or other forms.
What is Chemical Energy?
Chemical energy is the energy of chemical substances that is released when they undergo a chemical reaction and transform into other substances.
What is potential Energy?
Potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors.
What is Kinetic Energy?
The kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.
The break up of the conversions is:
Chemical energy from Jay's body to mechanical energy to wind up the key. Upon wind up the key, mechanical energy converted into potential energy within the spring. Next, the spring tries to releases itself and the potential energy is converted into kinetic energy as the toy car moves forward.
