3. Review Instructions You will complete your study guide during the game – if you don’t pay attention, you will not have a study guide!! I will choose players at random to switch from team to team as needed. Questions have different point values – yay!

4. 1. ______ is the energy of hot objects. Thermal 10. What does the law of conservation of energy state? That energy can not be created or destroyed, but transforms to a different type.

5. 8. What is Mechanical energy? The sum of potential and kinetic energy; does work 16. What is an insulator? Give two examples. An item in which electrons (electrical energy) can NOT easily flow through. Rubber, wood, cloth, plastic, etc.

6. 22. What does it mean when a circuit is closed? The circuit has a complete and unbroken path for the current to move. 11. Car A is parked on a hill and Car B is driving down a level highway. What types of energy do each of the cars have? Car A has potential energy and Car B has kinetic energy.

7. 18. A light bulb is an example of _______________ energy being converted in ________________ energy? Electrical; light 3. ________________________ is the energy used by your body and allows you to move/walk. Chemical energy

8. 2. ________________________ is energy from electrons moving. Electrical energy 13. A student wants to give a demonstration of elastic energy in class. What objects should he use for his demonstration? Rubber band, spring, hair tie, trampoline, etc.
