Basic Forms of EnergyBy: Mary TweedyEdited by: Kelly Richardson

What is Energy?

Energy is the ability to do work.

Energy is the ability to cause a change. Energy can change an objects: motion shape temperature color

Energy cannot be created nor destroyed

Energy is all around us!

You can see energy as light from the sun or a lamp.You can feel it as heat warms things up.You can see motion energy every time you move.

You use energy when you:

Take a walkLift a book Throw a ball

*What is light?

Light is something that allows us to see objects.Light is a form of energy. Light is produced by the vibrations of electrically charged particles.

What is Sound?https://www.pearsonsuccessnet.com/snpapp/login/login.jsp

Sound is a form of energy produced by a vibration or a back and forth movement of an object.Sound is a wave of vibrations that spread from its source of its matter.The more vibrations the waves have, the more energy, the louder the sound.The faster the vibrations or the frequency, the higher the sound.How high or low a sound is called the pitch.

Heat Energy?Heat energy flows from warmer substances to cooler substances.Heat is transferred from one object to another in three different ways:

Conduction

Convection

Radiation

What is electrical energy?A form of energy that is produced when electrons move from one place to another.Electrons are particles that are in the space around the nucleus of an atom.The forces of attraction and repulsion make electrons move.https://www.pearsonsuccessnet.com/snpapp/login/login.jsp

Chemical EnergyChemical energy is made when substances react and form new substances. Food, batteries, and fuels such as oil and gasoline are stored chemical energy.Chemical energy can change to:soundlightheat electrical motion

Energy of MotionEnergy can cause motion and create change.Car movingA person WalkingA ball bouncing
