  1. Do Now: Focused Free WriteLook at the bottle of clear solution on my desk, what do you think it is? Does it have ENERGY?

  2. Do Now: Copy HW & Lab Pass UP -Pass up Water Shoe box lab Monday: No HW Tuesday: Energy Homework Wednesday: Energy Transfer Practice Question in Packet on Page 7 Thursday: Specific Heat WS Friday: No Homework Extra Help: Thursday Morning

  3. Stop Monkey-N-ing around and Go Green already! P.S. I’m Mookie the Monkey Unit 1: ENERGY

  4. What is ENERGY? Energy is the ability to do _______ Work

  5. force move Work occurs when a _____ causes an object to _____ in the same direction as the force.

  6. FORMS OF ENERGY Both basic states of energy, Kinetic and potential, can exist in many forms!

  7. THERMAL (HEAT) Kinetic The total ________ energy of the particles in matter. (molecular motion)

  8. SOUND A type of mechanical energy. It is the energy produced when objects ________. Ex: tuning fork, bell vibrate

  9. MECHANICAL moving Energy with which ______ objects perform work. Ex: Wind, flowing water, using a hammer

  10. ELECTRICITY A form of energy produced by the ________ of ________ movement electrons

  11. CHEMICAL bonds Energy STORED in chemical ____ that can be released. Ex: food, fossil fuels, battery acid

  12. STORED MECHANICAL ENERGY: Stored energy due to a change in the shape of an object. Ex: _______________ A stretched rubber band

  13. STORED MECHANICAL ENERGY:

  14. LIGHT radiant wave A form of _______ energy that moves in a ______. Ex: lamp, stars

  15. SOLAR ENERGY SUN All forms of energy that come from the ______.

  16. NUCLEAR nucleus Energy STORED in the ________ (center) of an atom. Ex: nuclear bombs

  17. GEOTHERMAL (HEAT) Earth Heat energy STORED within the _____. Ex: Volcanic eruptions, geysers

  18. All forms of energy can be classified as Kinetic or potential. The two basic states of energy. So, what’s the difference?

  19. POTENTIAL ENERGY 1) Potential energy is stored energy due to and object’s _____________ Position

  20. POTENTIAL ENERGY gravitational 2) An object that is lifted from its position on Earth has __________ potential Energy which depends on ______ and mass height

  21. POTENTIAL ENERGY more 3) Massive objects have _____ potential energy than less massive objects

  22. POTENTIAL ENERGY more 4) An object at a higher elevation will have _____ potential energy than an object at a lower elevation

  23. KINETIC ENERGY Motion Kinetic is energy of ___________

  24. KINETIC ENERGY MASS SPEED 2) Kinetic depends on the _____ and the _______ of an object.

  25. KINETIC ENERGY More 3) Faster objects have ____ kinetic energy than slower objects.

  26. REVIEW QUESTONS: WHICH SKIIER HAS THE GREATEST KINETIC ENERGY? A B D C

  27. WHICH SKIIER HAS THE GREATEST POTENTIAL ENERGY? A B D C

  28. ENERGY TRANSFORMATIONS Do you remember the LAW OF CONSERVATION OF MASS AND ENERGY?

  29. Law of Conservation of ENERGY: (same for mass) Can’t be made Mass/ NRG ____________ Mass/ NRG ______________ Mass/ Energy can only __________ Can’t be destroyed Change form!!!

  30. DURING ENERGY CHANGES, IF ONE BODYIS LOSING ENERGY, THE OTHER IS _______ ENERGY: Gaining THE WAVE LOSES ENERGY: THE SAND GAINS ENERGY

  31. DURING ENERGY CHANGES, IF ONE BODYIS LOSING ENERGY THE OTHER IS GAINING ENERGY: THE WAVE LOSES ENERGY: THE SAND GAINS ENERGY

  32. DURING ENERGY CHANGES THE TOTAL ENERGY REMAINS THE SAME ENERGY ALWAYS FLOWS FROM HIGH TO LOW (source to sink)

  33. THE ENERGY WILL FLOW FROM: THE FLAME TO THE FINGER

  34. ENERGY WILL FLOW FROM ICE THE FINGER TO THE ICE

  35. THE LIQUID LOSES ENERGY AS THE ICE GAINS ENERGY

  36. WHEN WILL THE EXCHANGE OF ENERGY STOP? WHEN EQUILIBRIUM IS REACHED THE LIQUID AND THE ICE REACH THE SAME TEMPERATURE

  37. UNUSABLE ENERGY: heat Very often during the energy transformation process, some ____ energy is produced due to friction. This is wasted energy and is lost to the environment.

  38. ENERGY TRANSFORMATIONS Example: A television changes electrical NRG into light and sound NRG

  39. ENERGY TRANSFORMATIONS

  40. Do Now • Convection Box Demonstration

  41. Methods of Energy Transfer

  42. high Energy moves fromregions of _________concentration to ________concentrations of energy. low

  43. _______ To _______ Source sink

  44. There are 3 methods of Energy Transfer • Radiation • ConDuction • ConVection

  45. ConDuction

  46. Explanation of Transfer Direct contact (touch) Molecule To Molecule
