Summary Introduction

To write:

Different forms of energy.

Introduction:

Energy can be defined as the ability to work or cause change. It also comes in several distinct forms. However, energy can convert from one form to another. The various forms of energy are discussed below.

Explanation of Solution

The different forms of energy are as follows:

• Kinetic energy generates through the motion of the object. The example involves swinging on a swing.

• Potential energy reflects the stored energy of the object. For example, throwing the ball.

• Mechanical energy generates due to movement of the object and is the collective form of kinetic energy and potential energy. An example includes a moving car.

• Thermal energy indicates the energy of moving atoms within a substance and the atomic movement increases with the rise of temperature. For instance, a cup of hot coffee.

• Nuclear energy generates due to the changes in the nuclei of atoms or through nuclear reactions. For example, nuclear fission.

• Chemical energy results from the chemical reactions when the bonds break between atoms or molecules. The example involves electrochemical cell or battery.

• Electromagnetic energy or radiant energy generates from electrical and magnetic waves. For instance, radio and gamma waves.

• Sonic energy generates from sound waves because of vibration of atoms or molecules. It can travel through air, water, or another medium. The example includes a person’s voice or singing a song.

• Electrical energy results from the movement of electrons. For example, lights.

Conclusion

Energy mainly exists in seven different forms such as mechanical energy (kinetic and potential energy), thermal energy, nuclear energy, chemical energy, electromagnetic energy, sonic energy, and electrical energy.
