1. For the first three slides, each type of energy should be matched to a written definition and a picture that represents that type of energy. The slides show the correct placement of the flash cards and can be printed and used as an answer key.

2. chemical energy mechanical energy thermal energy Energy stored in chemical bonds; usually a substance has to burn to release this type of energy. energy an object has if it is moving The energy an object has because of the movement of its particles; heat energy; friction always produces at least a small amount of this type of energy

3. nuclear Radiant or electromagnetic Sound energy Energy released when the nuclei of atoms are taken apart or put together This form of energy can go through empty space; light energy This form of energy is caused by vibrating particles and cannot go through empty space.

4. electrical energy potential energy kinetic energy This type of energy involves moving electrons, usually through a wire or cord. Stored energy; energy that an object has due to its position or condition; depends on mass and height. The energy of an object that is moving; depends on mass and speed.

5. In the next slide, the twelve cards in the left column are matched in sets of two. The slide shows the flash cards in the correct placement and can be printed and used as an answer key. (ex: a kite stuck in a tree shows potential energy) The nine cards in the right column show energy transformations and are matched in sets of three. The slide shows the flash cards in the correct placement and can be printed and used as an answer key. (ex: a fire transforms chemical energy into thermal energy and radiant energy.

6. potential energy thermal energy electrical energy potential energy mechanical energy moving blades thermal energy radiant energy Transforms electrical energy into ______. mechanical energy Transforms mechanical energy into ________. electrical energy chemical energy transformed into ___ energy + ____energy
