8 Different Forms of Energy

Energy is necessary for any and all living species to exist. We get a huge portion of our sun's energy, and therefore it is our major source of power. The term "Energy" has many different connotations in our everyday lives, but it has a precise explanation in Science. 

 

The term "Energy" comes from the Greek word "Energia," which means "action or operation." Energy is defined as a physical amount transmitted from one item to another in order to perform labour or heat the object. The S.I. Unit Energy is measured in Joule (J), which is a derived unit.

 

Energy has always been crucial to how much we have progressed, from ancient civilizations to today's modern society, and to continue this growth, we are progressively trying to find new ways to harvest the many sources of energy to power our globe!

 

Although we are all accustomed to popular sources of energy such as electricity, wind energy, and the increasingly popular propane energy - due to their use in powering our everyday lives, there are actually eleven more that you must be familiar with. In this post, we'll look at the many sources of energy and how they assist power civilization, allowing us to live a pleasant and productive existence.

Did You Know?

 

When a shooter pulls upon that bow and pulls back the cord in the situation of a bow and arrow, part of the chemical energy in the archer's body is turned into potential and kinetic energy in the bow's bent forearm. 

 

Whenever the string is loosened and the arrow begins flight, the potential energy of the bow limbs is transferred into the kinetic energy of the projectile. As a result, whenever the string is released, the pressure between both the bow and string work on the arrow.

Different Forms of Energy

 

1. Kinetic Energy

 

Formula: K.E. = ½ MV2

 

Kinetic energy is the energy that an object has when it is in movement. It does not, however, have to be a physical thing, such as a moving automobile or bicycle. The motion of vibrations, atoms, and chemicals all result in the generation of kinetic energy.

 

The wind, which continually surrounds us while we are outside, is a fantastic example — the air movement of molecules and we perceive its kinetic energy when the wind is blowing against us.

 

Today, governments have erected wind turbines with massive revolving blades at extremely high elevations to collect kinetic energy from the wind and create power.

 

2. Gravitational Potential Energy

 

Formula: U = mgh

 

Consider raising a book several feet above the surface. Although the book is technically stationary, it does contain a type of energy known as gravitational potential energy. It is a type of natural energy which can be used in the future.

 

The more gravitational potential energy an item has absorbed, the higher it is and the bigger it's mass. This scientific premise is what drives the development of hydroelectric dams.

 

Hydroelectric dams exploit the potential energy of massive quantities of water held at high altitudes. The Hoover Dam in the United States, for example, can retain approximately 28.9 million acre-feet of water at an elevation of more than 200 metres.

 

Because water generally flows in a specified direction, by constructing a dam, the kinetic energy is stopped and turned into gravitational potential energy that may be used.

 

3. Mechanical Energy

 

Formula: EMechanical = U + K = mgh X ½ MV2

 

Mechanical energy is the energy produced by an object's motion or changing of position. And is the product of kinetic and potential energy.

 

A satellite in space circling Earth, for example, contains mechanical energy because it has simultaneously kinetic energy out of its motion and potential energy from Earth's gravitational attraction. Mechanical energy is converted into energy by machines in power plants, wind turbines, and hydroelectric dams.

 

4. Nuclear Energy

 

Formula: E = mc2

 

Nuclear energy is derived from the stored energy in the nucleus of atoms. To extract this energy, either fusion power or fission power will be required.

 

Nuclear fusion happens whenever atom nuclei join to generate larger nuclei, releasing massive quantities of energy in the procedure. This is the effective combination through which the processes in the Sun create energy. Nuclear fission, on the other hand, is the process through which nuclear power plants produce electricity on large scale energy.

5. Sound Energy

 

Formula: W = WPotential + WKinetic

 

Did you even know that sound is also a type of energy? Sound energy is simply the transfer of energy via what are recognized as sound waves, and it cannot flow in a vacuum since it requires a medium, such as the surrounding atmosphere.

 

You are transforming numerous sources of energy (such as kinetic energy) into sound energy if you are chatting, whistling, playing a rhythm set, or just clapping your hands.

 

Although there is no large-scale technology for converting sound energy into electrical energy, researchers are investigating piezoelectric transducers to gather sound wave energy in the hopes of converting it into useable electrical energy.

 

6. Elastic Energy

 

Formula : U = ½ kx2

 

Elastic energy is a type of potential energy that is held inside an item when it becomes strained. It is among the lesser-known sources of energy.

 

When you pull backward a bowstring, for example, elastic potential energy is created, which is transferred to the projectile you were just about to shoot and converted into kinetic and sound energy.

 

Simply tugging the endpoints of an elastic band imbues it with elastic energy, and if you let off, the elastic breaks back into its original form, releasing kinetic energy.

 

7. Electromagnetic Energy

 

Formula: E = h = hc

 

Electromagnetic or radiant energy manifests itself in observable waves known as light or unseen waves such as electromagnetic radiation and x-rays.

 

We may experience the impacts of the sun's energy – both heat and light – as well as many other more pleasant electromagnetic radiation such as UV light because radiant energy can move across space. The sun's rays are said to have radiant energy that extends beyond simply brightening our days and lighting the world.

 

Plants rely on sunshine, water, and carbon dioxide for photosynthesis, which produces oxygen as a waste product and helps the planet reduce greenhouse gas emissions.

 

India, for example, expects to create 100 GW of solar power by 2022, with roughly 40 GW coming from decentralized rooftop installations on rural houses to enable communities and families to obtain greater access to a higher living standard.

 

8. Electrical Energy

 

Formula: E = QV

 

In the end, there is electrical energy, which is perhaps the most important sort of energy about which we depend to operate our modern lifestyles.

 

The passage of electric charges generates electrical energy (or electrons). The quicker the electric charges flow, the more energy can be created.

 

However, due to the enormous demand for electricity, converting other sources of energy is the preferred method of generating electricity consistently and constantly to help power the gadgets in our homes and enterprises - from our 24/7 freezers to sophisticated electric automobiles.

The Transformation of Energy

 

You may change the shape of energy or transition it from one condition to another. Consider what would happen if the textbook was knocked off the desk. As the book falls, kinetic energy is released. Some of the potentials in the book are converted into heat energy as a result of the collision. 

 

Sound waves are created since some of the energy is converted into mechanical energy by the "SMACK !" that happens when the book collides with the ground. Using this concept with water in motion may be much more effective!

 

Falling water's kinetic energy is often turned into mechanical (rotational) kinetic energy. This power is then utilized in a machine to generate electrical energy, which is subsequently converted into thermal energy by heating the home with an immersion heater and a resistor. 

 

Energy transformation is intentional since the final use, i.e. the desired goal decides the form the energy will take. Using falling water to generate thermal energy helps us to heat our houses in the winter by capturing its energy. The conversion of potential energy in a bit of timber into radiant energy produces light and heat.
