Forms of Energy: 9 Different Types of Energy in the Universe (2023) » Tech Arbiters (2023)

Energy or force is the necessary element to do any work. Energy can neither be created nor destroyed. It changes forms from one to the other. The forms of energy are kinetic, thermal, electrical, chemical, nuclear, mechanical, radiant, potential, or kinetic.

Depending on the work, the energy state can be changed, transformed or converted. For example, if an apple is hanging on a tree, it has potential energy stored up.

It hangs down due to gravity and the kinetic energy is not enough for an apple to fall down. However, when an apple falls, it has kinetic energy.

When it hits the ground, it generates thermal energy due to the impact. In addition, you will hear the sound of smashing, which is mechanical energy.

Therefore, in this case, energy is converted intoPotential Energy > Kinetic Energy > Thermal Energy > Mechanical Energy.

Energy is present in every thing that belongs to the universe. In addition, the amount of energy will remain as we received it from the past. But the forms of energy will change each time.

There are several types of energy in the universe that humans have successfully identified. There could be more as experiments stretch beyond the horizon.

In this article we will see all the different types of energy that exist in different forms. Using examples, all types of energy are easy to understand and you provide information about all forms of energy.

9 different types of energy:

1️⃣ Mechanical energy

Mechanical energy can be related to the motion or stationary position of an object. During motion it is in the form of kinetic energy, otherwise in the form of potential energy. Objects using mechanical energy to do work in many forms.

For example, when fuel burns in the engines, it generates electricity in the form of mechanical energy to power the car. In this case, thermal energy as output power is converted into mechanical energy.

The same process takes place in steam engines, where hot steam creates pressure and moves the train in every direction.

In hydroelectric power plants, the kinetic energy of the water moves the blades of turbines and is converted into mechanical energy to generate electricity.

2️⃣ Electrical energy

Electrical energy depends on the movement of the electron. There are three ions present in atoms, protons (positive ions), electrons (negative ions), and neutrons (neutral ions).

External forces such as magnetic or electric fields cause electrons to move and change their position. This change in the movement of the electrons generates electrical energy. The amount of energy depends on the movement speed.

Electrical energy can be generated by converting kinetic energy. In the case of turbines, the rotary or radial force is required to drive the turbine, which is connected to the generator's shaft.

The turbine produces kinetic energy for the generator. As the generator shaft rotates, it converts kinetic energy into electrical energy. These forms of energy generally provide electricity in different formspower plants.

3️⃣ Thermal energy

The thermal or thermal energy is generated when electrons present in the atom begin to vibrate due to external forces such as temperature, impact or friction.

Initially, electrons are in a normal state, and due to the force, they move and vibrate, generating thermal energy.

It always depends on how strong the force is to evaluate the amount of thermal energy. The objects eventually remain at the same temperature as the room or environment after the vibrations subside.

For example, when you heat the metal plate, electrons start vibrating, converting potential energy into thermal energy.

After some time. Vibration is reduced and temperature drops as metal plates close the heat or heat energy. These types of energy are involved in steam generation or cooking.

4 ️⃣ Nuclear energy

Nuclear power uses a method called "nuclear chain reaction" to create energy. Nuclear fission occurs when two atoms split together and one atom gains energy.


This is a very fast chemical reaction and typically a chain reaction occurs. The amount of energy gained depends on the number of different nuclei involved in the reaction.

When a chain reaction occurs, neutrons are split, releasing energy as either kinetic or electrical energy.

Nuclear energy is considered to be one of the most efficient and reliable sources of electricity generation. However, the construction of nuclear power plants requires many safety measures. In addition, these forms of energy also causeradiationif there is a leak.

5️⃣ Radiant Energy

Radiant energy is one of the forms of energy related to the movement of photon particles or electromagnetic waves.

Some waves or lights are invisible to humans, such as X-rays, radio waves, or ultraviolet rays. However, the effect of these lights is important in many areas.

In nature, sunlight is a great source of radiant energy. Photosynthesis process for plants and trees, vitamin D for the human body, warming up and lighting up the other planets are possible through this form of energy.

What radiant energy is in physics is that it has no limitations. It can be used anywhere there is an unrestricted heat source. This means you can use it to heat your home, car or pool.

Radiant energy is used by people all over the world for various things. Some people use it to heat their homes while others use it to power their cars. Many of us use it to run our devices and power our GPS systems.

6️⃣ Chemical Energy

To understand chemical energy, you must first understand the chemical process. When two different chemicals are mixed, a new compound is formed. After that, they go through a reaction and produce a new substance. All of these reactions generate chemical energy.

Now, for example, let's say we take some hydrogen and oxygen molecules and put them together. We can find the sum of the energies by dividing the total by their individual values.

The process of combining the two produces HHO, or Brown's Gas, a type of high boiling point compound.

When we add heat to this mixture, we get water vapor, which turns into HHO gas. Now we have a chemical reaction taking place between the molecules, turning them into HHO gas.

7️⃣ Magnetic energy

Magnetic energy is generated by an object undergoing a change in magnetic field. Basically, a magnet generates its own energy when held close to the surface it is placed on.

There are two magnets of action that can create attraction and repulsion. When two poles of the magnet come together, magnetic energy is generated in the form of repulsion. While two opposite poles create an attractive form of energy.

Just like a magnet, the earth is also a large source of magnetic energy that creates gravitational force and pulls objects to the earth's surface.

8️⃣potential energy

Potential energy is present or stored in every object. When no external force acts on an object, the amount of potential energy remains the same, e.g. B. a box on the table or petrol in the car.

As soon as external forces act on the object, it loses potential energy and changes the form of energy like kinetic energy or thermal energy.

For example, if we take a spring and a compressed spring, they have the same amount of potential energy but in opposite directions. Because of this, when you compress a spring, you create a torque that compresses the spring and moves it.

9️⃣Kinetic energy

When an object has motion, it is due to kinetic energy. It is the change in velocity that gives these particles their kinetic energy.

For example, when two different sized balls are thrown together, they can gain or lose energy due to their momentum. It depends on the mass of the balls how long they can travel.

When the ball stays in the hand, it has potential energy, when the momentum starts due to the external force, it has kinetic energy.

Kinetic energy is also divided into two main categories. These categories are kinematic and kinetic. Kinetic energy is the amount of energy required to travel a distance in physical motion.

For example, if a sailboat moves at the same speed as the wind while sailing at the same wind speed, it also has the same amount of kinetic energy.

In contrast, kinetic energy is the amount of energy required to do work or move an object from point A to point B.

Conclusion: forms of energy

In summary, there are many forms of energy that can be transmitted, transformed, or transformed into different forms. The rate of change depends on the object's mass and external forces.

There are 9 types of energy, generally sufficient to carry out any task or remain involved in any task. However, some other types of energy can be considered, such as B. gravitational force or electrostatic attraction.

You can get multiple forms of energy at once, but ultimately the amount of energy stays the same.
