1. ENERGY TRANSFER

2. LAW OF CONSERVATION OF ENERGY no energy is created of destroyed as it changes form example: the amount of heat and light energy given off by a flashlight equals the amount of chemical energy released by the battery. energy can escape a system but it is not destroyed

3. TRANSFERRING ENERGY energy can be moved from one object or place to another example: light energy from a flashlight is transferred as it lights a room anything that seems to make energy is just changing its form

4. ENERGY TRANSFER EXAMPLES 1. fire changes chemical energy in the wood to heat energy and light energy 2. cell phone changes electrical energy into sound energy 3. a drum changes kinetic energy from the drummer’s hands into sound energy

5. ROLLER COASTERS as the roller coaster goes up the first hill, potential energy increases once you start down the hill, gravity takes over and the potential energy is changed to kinetic energy as the rollercoaster goes back up the next hill, the kinetic energy turns back into potential energy roller coaster clip
