Types of Energy by Arnold, Savannah

Definition of Energy

Energy is defined as the ability to do work. An object that has energy performs work. Energy's also used to maintain a process or carry out an action.

Energy Transfer

842090_2 — 2024-02-12 21:51:07 UTC

Energy can transfer from one object to another. Energy can also transfer from one location to another.

The Law of Conservation of Energy

842090_2 — 2024-02-12 21:53:23 UTC

The Law of Conservation of Energy, is similar to the Law of Conservation of Mass, being that it states energy cannot be created or destroyed.

Energy Transformation

Because energy cannot be created or destroyed, energy instead changes. For example, when you have wind mills the mechanical energy changes into electrical energy, then finally into things like light energy for light bulbs (etc.) Energy transformation is the conversion of energy from one form to another.

Mechanical Energy

Mechanical energy is the energy of motion. It is the energy that makes things move. For example, a wheel spinning has mechanical energy because it is moving, spinning and changing positions.

Light Energy

Light or also called radiant energy, is carried by light. Visible light, like the sun, is made up of electromagnetic radiation, this is visible to the human eye. Though, all electromagnetic radiation has energy.

Electrical Energy

Electrical energy is carried by charged particles. Electrical energy is also called electricity. Did you know when you charge your phone your using charged electrons, hence the name. Charged particles can build on an object and creates static electricity. For example, when you rub your hands or feet on a carpet then touch someone's hand, you shock them. Current electricity moves along a path called a circuit.

Sound Energy

Sound energy is carried through sound waves. These sound waves can travel or go through matter. For example, when you hear people talking in another room, or hear someone scream under water. Sound energy is created when something vibrates, like a speaker.

Thermal Energy

842090_2 — 2024-02-12 22:29:55 UTC

Thermal energy is associated with temperature. Thermal energy can be either hot or cold. When atoms move faster in matter things get hotter, but when they slow down it produces more cold temperatures. Did you know that a hot object has more thermal energy than a cold one. The amount of thermal energy in a substance has to do with the substance's temperature as well as the amount of matter in the substance.

Chemical Energy

842090_2 — 2024-02-12 22:33:36 UTC

Chemical energy is the energy stored within the bonds between atoms in matter. This is used to keep the atoms bonded together. The bonds between atoms in food and fuel store a lot of chemical energy. For example, when a person digests food, the bonds break and chemical energy is released. When fuel is burned, the bonds break and chemical energy is released.

Can Energy Be Created Or Destroyed?

842090_2 — 2024-02-13 21:59:41 UTC

No, energy cannot be created or destroyed. As it says in the Law of Conservation of Energy, "Energy cannot be created or destroyed." This said, energy can change from one form to another. This law has never been broken and probably never will be.

Can an Object Transfer More Than One Type of Energy?

842090_2 — 2024-02-13 22:04:57 UTC

Yes, an object can transfer more than one type of energy. For example, when a lightbulb is lit, it gives off both light/radiant energy, but also thermal energy. Another example is when you light a campfire the wood burns and gives of thermal energy, while also giving off light, as radiant energy. This proves that an object in fact can give off more than one type of energy.

Can Energy Change?

842090_2 — 2024-02-13 22:22:04 UTC

Yes, energy can change. An example of this is when sun rays (light/radiant energy) go onto a solar panel, it then gets processed and turns into electrical energy, then it produces actual electricity. That means it could light a lamp, or turn on a fan, and even heat up water. This proves that energy can change to different types of energy.

How Does Energy Flow in a System?

842090_2 — 2024-02-13 22:32:59 UTC

As you can see the energy flows from the girls body as chemical energy, then flows through the pedals as mechanical energy. Finally, it flows into the pipe as electrical energy, and heats up the water as thermal energy. Energy flows, and it never seems to have a final destination to where its going.
