Different types of energy with Cinnamoroll !! Santiago V and Celine by Vazquez, Santiago

There are many different types of energy such as mechanical, chemical, physical, light, electrical, and sound. But what is energy? Well, energy is anything that can do work. What that means is anything that can apply force, change or move something.

Digging deeper into the different types of energy, let's begin with mechanical. Mechanical energy is the energy of movement. It is used to hold, lift, drop or move something.

For example, riding a bike is converting kinetic energy into mechanical energy!

Sound energy is energy that travels through sound waves. It has the ability to travel through matter and water, but it may not sound the same. It is created when an object vibrates.

As an example, listening to music is sound energy because it travels with sound waves.

Another type of energy that is considered one of the main 6 type of energies is Chemical Energy. Chemical Energy is energy stored in the bonds of atoms. Its purpose is to keep atoms bonded together.

For more information, here are videos explaining what Chemical Energy is!

Another of the main energies is light energy. Also known as radiant energy. What it is refers to energy carried by light, or visible light. Infared vision, UV light, x-rays and many more are all light energy.

The sun is a form of light energy because it produces light to land around on the earth and us.

Electrical energy is energy that is carried by charged particles, or electrons. It is the energy that charges things like phones, computers, iPads and more. They can also move from place to place creating an electric current.

The last energy that is considered to be one of the main 6 types of energy is thermal energy. Thermal energy is associated with temperature. Thermal energy is caused by the motion of molecules and is the cause of heat transfer!

The bonfire in this image is emitting heat which is associated with the concept of Thermal Energy.

Energy can change from the original energy to a different one. For example, electrical energy can change into light energy in a flashlight. Or it can turn into sound energy from a speaker. Thats what energy transformation is. It's one energy changing to another. Like in the example, it can be one energy changing to a completely different one.

Energy transfer is when energy moves from one place to another. An example of energy transfer is the electric energy moving from the brick of your charger to your phone to be able to charge it.

The law of conservation of energy is a scientific law that states the inability of inventing and decimating energy. In other words, energy cannot be created or destroyed.

842598_3 — 2024-02-13 22:02:00 UTC

So know we have some questions for you after reading. The first one is, can an object transfer more than one type of energy?

842598_3 — 2024-02-13 22:06:18 UTC

The answer is yes, an object can transfer more than one type of energy! However, most of the time, the second type of energy that is transferred along with the first type of energy is waste energy. Waste energy is energy that is not usefully transferred. For example, a kettle converting thermal energy to mechanical energy may have bits of thermal energy being released from the kettle!!

The next question is, can energy change to different types of energy?

842598_3 — 2024-02-13 22:19:49 UTC

The answer is yet again, yes! using an example of a cell phone, the electric current can change from its original form as electric energy to light energy with its flashlight or even thermal energy because of the brick getting hotter the longer it is left plugged in.

Another question is, can energy be created or destroyed?

952790_1 — 2024-02-13 22:24:09 UTC

As stated in The Law of Conservation of Energy, energy cannot be created or destroyed. This has been proven multiple times in many different experiments executed by scientists. To put simply, energy cannot be invented or eliminated.

The last question is how does energy flow in a system?

842598_3 — 2024-02-13 22:35:01 UTC

In an energy system, energy converts itself from one form to another. For example, in this image, the thermal energy from the heat below the kettle converts into mechanical energy when transferring out of the kettle and into the generator. After that, the energy then enters the wire becoming electrical energy. Since the wire is connected to the light bulb, the electric energy becomes thermal energy!
