Types of energy by Santiago, Rico

Energy is the ability to do work. Work is considered as the ability to move or change things by applying force. This is like when wind pushes plastic on the ground.

The law of conservation of energy is energy cannot be created or destroyed. An example of this is when you light up a lightbulb, the electrical energy turns into thermal then radiant energy.

There are six types of energy, Mechanical, radiant (or light), electrical, chemical, thermal, and sound energy.

Light energy is energy carried by light, usually visible light. Some types of light are UV, Infared light, and X ray. Visible light is on the electromagnetic spectrum.

Mechanical energy is the energy of movement. This includes holding and moving things. For example, when you want to pick up a glass of water you use mechanical energy and move the glass.

Thermal energy is the energy of heat, whether it is the high amount of heat or the lack of heat. When atoms vibrate faster or slower it changes the heat. This energy is like your freezer at home because of the cold temperature it produces.

Chemical energy is the energy of stored energy. This energy is within the things that keep atoms together called bonds. This energy is like when you eat a French fry, the stored energy from the French fry is turned energy for your body.

Electrical energy is the energy carried by the part of the atom called the electron. This energy is like when you plug in your phone, and it gains battery.

Atoms are what make up everything in the physical world and are the smallest thing of a pure element (like water).

Sound energy is carried by sound waves, it creates vibrations, and can travel through matter, or anything made up of atoms, meaning different states of matter having different effects on sound. An example of sound energy is when you listen to music the sound waves produced reach your ears.

All energy falls into two categories. Kinetic energy, the energy of movement, and potential energy, which is stored energy. for example, when someone is about to throw a baseball, it is potential energy until it is thrown, once it is thrown it becomes kinetic energy.

Energy transformation is when one type of energy turns into another. An example of this is when you eat a pizza then go build Lego's, the chemical energy of the pizza converts to mechanical energy when building Legos.

Energy transfer is when one energy transfers from object to object or place to place. The energy does not change during transfer, so this means the energy same during this process. An example of this is when electricity moves through wires.

Energy can change from one element to another. This is shown when plants photosynthesis. When plants do this process they take the energy from the sun ( radiant energy) and create food for themselves, chemical energy.

156113_11 — 2024-02-15 00:18:10 UTC

Energy cannot be created or destroyed. This is stated in the Law of conservation of Energy. This law states energy cannot be created or destroyed, instead changing forms.

156113_11 — 2024-02-15 00:30:31 UTC

Energy cannot transfer more than one type of energy. This is shown by what energy transfer is. Energy transfer is the movement of energy from place to place or object to object and the energy can only be a single type. For example, a campfire only makes thermal energy, but creates different things with the energy like smoke and sparks.

Energy flows in different sequences or systems. As in the picture seen here, the water faucet starts off as mechanical energy. As the water produces it spins the wheel transforming the mechanical energy into electrical energy, then the electricity turns into thermal and radiant energy. This is the energy shown when using a light bulb.

Waste energy is the type of energy made in the process of powering something, that is not the intended purpose of the object. For example, when a light bulb is turned on, the sequence is mechanical energy, electrical energy, and thermal energy. The waste energy is thermal because the lightbulb is used for lighting up your house, not heating it.
