There are different forms of energy such as:
1. Solar energy:Â can be used to bring about electrical energy. It is gotten from the sun.
2. Heat energy:Â can be used to produce steam, used by steam engines to do work.
3. Light energy:Â when it falls on a light meter it is useful in photography.
4. Mechanical energy:Â (potential and kinetic).
5. Electrical energy:Â is used to drive the electric motor and for heating purposes.
6. Sound energy:Â it causes a microphone thin plate to vibrate.
7. Chemical energy:Â it is the energy stored in food and fuels.
All these forms of energy are convertible, that is, we can change energy from one form to another.
