Study Guide: Energy Words to know: Kinetic and Potential Energy Law of Conservation of Energy Forms of Energy: SCREAM (Sound, Chemical, Radiant, Electrical, Atomic, Mechanical) Gravitational and Elastic Potential Energy Energy Transformations Practice: Categorize as potential or kinetic: 1. A rock sitting at the edge of a cliff. 2. An insect flying 3. Tree branches high up in a tree. 4. A stick of dynamite 5. The food we eat has chemical potential energy because as our body digests it, it provides us with energy for basic metabolism. 6. A car traveling down the road 7. A river flowing at a certain speed 8. A stretched spring in a pinball machine 9. When a crane swings a wrecking ball up 10. A set of double "A" batteries in a remote control 11. An airplane flying 12. A baseball thrown by a pitcher 13. A golf ball sitting on a tee before it is struck. 14. An asteroid falling to earth at incredible speeds 15. A downhill skier traveling down a hill Energy Transformation: Determine how each item gets its energy and transforms it to another form of energy (or energies). Use SCREAM as the choices for each. Concepts to understand: 1) What is kinetic and potential energy? Give examples of each. 2) What different forms does energy come in? What are other words to remember these? Give examples of each? 3) How does energy change or transform from one type into another? Why? Give examples. Where does energy go when it’s no longer being used?
