What is Energy Transformation?

Energy transformation is the conversion of energy from one form to another.

For example, electrical energy can be transformed into heat and light energy, while chemical energy stored in food or fuel can be transformed into other forms of energy.

Mechanical energy can also change from one form to another. Potential energy can be transformed into kinetic energy, and kinetic energy can be transformed back into potential energy.

Law of Conservation of Energy:

The law of conservation of energy states that energy can neither be created nor destroyed, but can only be transformed from one form to another. Therefore, the total energy of an isolated system remains constant.

An isolated system is a system that does not exchange energy with its surroundings.

Conservation of Mechanical Energy:

Recall that mechanical energy is the sum of the kinetic energy and potential energy of a body.

Mechanical Energy = Kinetic Energy + Potential Energy

When only conservative forces such as gravity act on a body, and effects such as
