Forms of energy:

Energy can be of many forms. The different forms of energy include kinetic energy, potential energy, chemical energy, heat energy, electrical energy and light energy.

Kinetic energy is the energy possessed by a moving body. Any object under motion has certain kinetic energy. For example, a rolling ball, a flying bird, a swimming fish, a moving car, a falling leaf, a spinning top etc.

Potential energy is the energy possessed due to the position of an object. A book placed on a table possesses some potential energy due to the height at which the book is placed. Other examples include stretched spring, coconut on a tree or any object at a certain height.

Chemical is the energy stored in chemical substances. When a chemical change occurs, chemical energy is converted into other forms of energy like electrical, heat or light energy. For example, in batteries, chemical energy is converted into electrical energy. Burning of several substances produces heat and light energies. Burning of wood, coal, paper etc produces heat and light. Another common example is a burning candle. Also our sun is a major source of light and heat energy.
