Energy Transformations

Energy transformations occur when...

• energy is created through conduction

• energy changes from one form to another

• energy is destroyed through fusion

• energy is initially created then it is destroyed

The Law of Conservation of Energy states -

• Energy can be created, just not destroyed. It changes its form from one type to another.

• Energy can not be created nor destroyed. It can only change from one form to another.

• The total energy in our universe constantly changes, as different forms of energies can be transformed from each other under certain circumstances.

• Energy transformations do not passively occur in our lives, rather we actively make use of energies and transform energies.
