Different Types of Energy

Introduction to different types of energy:

It is often said that a person A is more energetic than a person B. The meaning of this statement is that a person A can do more work than the person B. Person A is said to have more energy. Energy is needed to do some work. After doing a lot of work, one feels tired and need more energy. Thus, anything which is capable of doing work has energy. The capacity of doing work by a body or an object is known as the energy of  the body or the object.I like to share this Rotational Kinetic Energy Formula with you all through my article.

Energy is defined as the ability or the capacity to do work.

Units of Energy:

Energy can be measured in Joules. Joule is named after an English physicist named James Prescott Joule who lived from 1818 to 1889. He discovered that heat is a type of energy. One joule is the amount of energy needed to lift 1 pound about 9 inches.

Types of Energy:

Kinetic Energy- The energy possessed by a body by virtue of its motion is known as kinetic energy. For example a moving bus, Moving bullets, flowing water etc.

Potential Energy-  The energy possessed by a body by virtue of its position or shape, is known as Potential energy. For example water stored in a dam , a stone lying on the top of hill, a wound spring of a watch, a stretched bow and arrow  etc.

Mechanical Energy- The sum of kinetic energy and potential energy of a body is known as mechanical energy.

Types of Energy:

Heat or Thermal Energy- The energy possessed by a body due to its temperature is known as heat energy. For example energy of hot water, energy of hot air etc.

Chemical Energy- The energy released in chemical reactions is known as chemical energy.
Sound Energy- The energy of a vibrating object producing sound is known as Sound energy.
Electrical Energy- The energy of moving electrons in a conductor connected with a battery is known as electrical energy.
Nuclear Energy- The energy released when two nuclei of light elements combine with each other to form a heavy nucleus or when a heavy nucleus breaks into two light nuclei is known as nuclear energy.

Solar Energy- The energy radiated by the sun is known as Solar energy
