The main transformation of energy is chemical energy to motion energy.
Jay's body converted chemical energy into mechanical energy to wind up the key. Mechanical energy in the key's winding was transformed into potential energy in the spring. The spring then strives to release itself, and as the toy car rolls forward, the potential energy is transformed into kinetic energy or motion energy.
Chemical energy is the energy that is released when chemical substances engage in a chemical reaction and change into other substances.
Potential energy is the power that an object can store as a result of its position in relation to other objects, internal tensions, electric charge, or other circumstances.
The energy that an object has as a result of motion is known as kinetic energy. It is described as the effort required to move a mass-determined body from rest to the indicated velocity.
