Energy is the ability to do work or cause change. ~*~Different Forms Of Energy~*~
<<<<Different Forms Of Energy>>>>
The major forms of energy are mechanical, thermal, chemical, electrical, electronmagnetic, and nuclear energy.
The law of conservation of energy states that when one form of energy is converted to another, no energy is destroyed in the process. According to the law of conservation of energy, energy cannont be created or destroyed.

3| | |Mechanical Energy| | |4

Mechanical Energy is the energy associated with the motion or position of an object. Mechanical energy can occur as kinetic energy or potential energy.
::Example:: A school bus, frog leaping through the air, even sounds you hear.

3| | |Thermal Energy| | |4

Thermal Energy is the total energy of the particles in an object. When the thermal energy of an object increases, its particles move faster, making it feel warm to the touch.
::Example:: Ice cream melts when its thermal energy increases.


3| | |Chemical Energy| | |4

Chemical Energy is potential energy stored in chemical bonds that hold chemical compounds together.
::Example:: It is stored in food you eat and in a match when you light a candle. It is even stored in the cells of your body.

3| | |Electrical Energy| | |4

Electrical Energy are charges that move to produce electricity, and the energy they carry electrical energy.
::Example:: Batteries, powerlies run electrical devises such as radios, lights, and computers.

3| | |Electromagnetic Energy| | |4

Light is a form of electronmagentic energy. It travels in waves. These waves have some electrical properties and some magnetic properties.
::Example:: Light, microwaves are different examples of electronmagnetic energy.

3| | |Nuclear Energy| | |4

Nuclear Energy is stored inside a nucleus of an atom and is released during a nuclear reaction. Nuclear power plants use fission reactions to produce electricity. Nuclear fusion occurs in the sun and other stars.

Fossil Fuels aren't very good to use because they are formed million of years ago from decayed plants and animals. Oil, coal and natural gas are such fuels. And they are formed by the decay of land vegetation. Oil is formed from the remains of marine microorganisms 9microscopic animal & plants). Natural gas is formed in the same way as oil, from the remains of marine microorganisms. The supply is not infinite, so we need to be careful the way we use them. If we use too much of something, it might run out and we won't be able to use it any longer.
