What are the Different Types of Energy?

The Law of Conservation of Energy states that Energy can neither be created nor destroyed but can be changed from one form to another. 

‍

Energy is a physical quantity that can be transferred from one object to another to perform work. The S.I. unit of Energy is Joule (J) named after the famous physicist James Prescott Joule. When one Newton (1N) of force is applied through one meter of distance, one Joule of energy is used. 

There are two forms of energy:

1. Kinetic energy 
2. Potential energy

1) Kinetic Energy (K.E): The energy that is generated as a result of the motion of the object is called kinetic energy. E.g., motion energy, thermal energy, radiant energy, and sound energy.

K.E = ½ mv²

Where m = mass of the object

             V = velocity

2) Potential Energy (P.E): The energy generated as a result of the position is called potential energy.  This energy is stored in the object. E.g., chemical energy, nuclear energy, mechanical energy, and gravitational energy.

P.E = mgh

Where m = mass of the object

             g = gravitational acceleration constant

             h = height above the ground
