Thermal Energy

All matter is made of particles that are

constantly in motion.

Thermal energy is the total potential and kinetic

energy of the particles that make up an object.

Chemical Energy

Chemical compounds are made up of atoms and molecules. Bonds between the atoms and molecules hold chemical compounds together. These bonds have chemical

energy.Chemical energy is potential energy

stored in the chemical bonds that hold chemical compounds together.

Radiant EnergyRadiant energy is energy carried by

an electromagnetic wave. Also called electromagnetic energy.

Electrical Energy

Electrical energy is the energy of moving electrons. Electrical energy can be either potential or

kinetic energy.

Sound Energy

Sound energy is caused by an object’s vibrations.

Sound is movement of energy through waves.

To make an object vibrate, work must be done to change its position. So sound

energy is a form of potential and kinetic energy.

Nuclear EnergyNuclear energy is stored in the nucleus

of an atom. (Potential energy)Nuclear energy is produced in two ways: 1. When two or more nuclei join together

(fusion)2. When the nucleus of an atom splits

apart (fission)

Energy TransformationWhy is the transformation of energy important to our everyday life?

Everything we do is related to energy conversions:

• toaster for your breakfast• energy from a meal• light a match• riding in a car

Law of Conservation of EnergyThe Law of Conservation of Energy says that energy is neither created nor

destroyed.

When we use energy, it does not disappear. We can change it from one form

of energy into another.

Energy changes form, but the total amount of energy in the universe stays the same.
