Forms of Energy
The following are the various forms of energyEnergy is the ability to do work. Energy exists in several forms such as heat, kinetic or mechanical energy, light, potential energy, and electrical energy. Units of Energy: The SI unit of energy is the joule (J) or newton-meter (N * m). The joule is also the SI unit of work.:
- Mechanical energy.
- Heat energy.
- Electrical energy.
- Chemical energy.
- Light energy.
- Sound energy.
- Nuclear energy.
- Magnetic energy.
1. Mechanical Energy:
This is the form of energy that a body possesses by virtue of its position or motion. There are two forms of mechanical energy.
a. Potential Energy: This is an energy a body possesses by virtue of its position.
b. Kinetic Energy: This is the energy of a body in motion.
2. Heat Energy:
This is a form of energy produced or derived from burning fuels. It is used to cook food, iron clothes, etc.
3. Electrical Energy:
This is a form of energy produced when electrons move through substances. It is used to operate fans, radio sets, etc.
4. Chemical Energy:
This is a form of energy contained in chemical substances such as food and fuels.
5. Light Energy:
This is a visible form of energy which is radiated from a source. It is a form of energy visible to the human eye that is radiated by moving charged particles.
6. Sound Energy:
This is the energy produced by vibrating objects e.g drum, guitar, etc.
7. Nuclear Energy:
This is the energy produced when an atom is split. It can be used for the production of electricity and for military purposes.
8. Mechanical Energy:
This form of energy results from a magnetic field.
