  1. Energy Transformations & Conservation

  2. Energy Transformations & Conservation http://www.youtube.com/watch?v=iotBJt2MaQM Niagara Falls Mechanical energy is transformed into electrical energy!

  3. Energy Transformations • A change from one form of energy to another form of energy. • Many forms of energy can be transformed into other forms.

  4. Single transformations A toaster transforms electrical energy into thermal energy What type of energy transformation is happening here?

  5. Single transformations What type of energy transformation is happening here?

  6. Multiple transformations • Mechanical energy • Thermal energy • Electromagnetic energy

  7. Transformations between potential and kinetic energy • Niagara Falls

  8. Energy transformation in juggling • Explain how energy is transformed when juggling

  9. Wile E. Coyote vs. Roadrunner • https://www.youtube.com/watch?v=Jnj8mc04r9E • https://www.youtube.com/watch?v=i6e-KrNCe_E

  10. Energy transformation in a pole vault • What kind of energy lifts a pole-vaulter over the bar?

  11. Law of Conservation of Energy Songs • https://www.youtube.com/watch?v=_uLSFigtLKg • https://www.youtube.com/watch?v=k60jGJfV8oU

  12. Law of Conservation of Energy • Energy cannot be created or destroyed, but it can be change from one form to another. • No energy is destroyed in the process of energy transformation.

  13. Energy and friction • If you set a spinning top in motion, will the top spin forever?

  14. Energy and friction • Mechanical energy is transformed into thermal energy • Friction= force one surface exerts on another when two surfaces rub together • fricción • Rub your hands together. What happens?
