Secret Lives Title - The Energy Story


Energy Types


In assignment 2, you tried to place the types, sources, and words associated with energy into 10 basic categories or types of energy. Since energy comes in so many forms and, as we will see, is also constantly changing from one form into another, selecting a perfect set of 10 basic types is not easy. Below are one possible set of 10 basic types of energy and the words from the list of assignment 2 that go with each type. You may have come up with your own perfectly reasonable set of 10 basic types that are somewhat different than the 10 listed below.

The 10 Types of Energy

Review the list below so that you can identify each energy's type before you continue. You can find a definition and more information by clicking on the energy type.

Also, each of these energies can be identified as either kinetic or potential. Kinetic energy is energy of motion - the energy is contained in the movement of the object or movement inside of the object. Potential energy is stored energy, energy that can be kept for use at a later time.

Some of the pages below have Macromedia flash animations that require the flash player. You can view the page without the flash player but you will not be able to see the animations. You can download and install the flash player from the following site: Download Flash Player
