Presentation transcript:

Two Kinds of Energy Potential Energy Stored energy, built up, waiting to be used. Example: If I am holding a book, about to drop it on the floor, it has potential energy, because it has the potential to use energy. Kinetic Energy Energy being used, energy in motion. Example: After I let go of the book, it has kinetic energy, because it is in motion as it falls and hits the floor.

Rlues for Catapults Do NOT aim it at any person in this room. Only launch the objects specifically listed in your experiment. Follow all of Mrs. Treherne’s directions. Keep the noise level down. Failure to adhere to these rules will result in a loss of catapult privelidges and an alternate assignment.
