5. Conservation of Energy

6. Potential EnergyKinetic Energy

7. It has always been around! –Even before the big bang! Energy CANNOT be created

8. Energy is never used up… Energy transfers from one object to another Energy CANNOT be destroyed!

9. Conservation of Energy –Energy is neither created nor destroyed, it merely changes form!

16. Conservation of Energy Lab Hot Wheelin’

17. Cut & glue the handout into your notebook Purpose… –To measure the energy into & out of a system 1m H Data: –M=50 grams (convert) –H=30 cm (convert) –Distance = 1.0m –Times… T1 -.50s T2 -.43s T3 -.57s

18. Pick one of the following energy sources and trace back the energy to a source 7/9/2016 Windmill Nuclear Coal Hydro-electric Bio-fuels

19. The law of conservation of energy states that energy is neither created nor destroyed. If this is true, why didn’t all the Potential Energy transfer to kinetic energy in the car? Where did that energy go? Discuss at least 2 ways you think you could reduce the amount of energy transferred outside the ramp & car system. Relate this experiment to a real life example of potential energy being transferred to kinetic energy? If you were to continue an experiment about energy transfer, what would be your next scientific question?
