1. CONSERVATION OF ENERGY Energy can neither be created nor destroyed; it can only be transformed from one form to another.

2. How much PE? How much KE?... In what direction?

3. Why doesn’t it hit your face? The total energy of a system must be conserved… But energy can be converted to: heat, sound, light, etc… and essentially is “lost”

9. 200 m 1 Liter of water has a mass of 1kg. If the dam allows 15,000 gal/sec (1gal = 3.78L) to flow through, what is the max amount of electrical power this dam’s turbines can put off?

10. Gas http://us1.webpublications.com.au/static/images/articles/i10/1066_10mg.jpg Chemical Potential ENERGY WORK done by Car

11. If gasoline has 1.32 x 10 8 Joule/gal of potential energy… and the engine is 20% efficient, how much gas will it burn for the 1600kg car to climb a 100 m tall hill? 100 ft

12. Place cup at known distance from ramp (you choose)… using what you already know plus the new energy/work stuff, calculate the height on the ramp you need to release a ball from to land it in the cup! If you succeed you are done… if not, determine the amount of energy lost to friction, air resistance… even sound.
