1. Warm up: at what point does the roller coaster have the most gravitational potential energy ? Activity 56: Shake the Shot

2. At what point does the roller coaster have the most kinetic energy ? Activity 56: Shake the Shot

3. Potential and Kinetic Energy in a Pendulum

4. Activity 54 Analysis Questions

6. Energy- can cause objects to change, move, or work. Potential energy- stored energy that has not been used yet. Gravitational potential energy- when potential energy is due to an object’s position above earth. Kinetic energy- the energy an object has when it is moving. Activity 54 In Case You Missed It…

7. The greater the mass or height of an object, the more potential energy it will have. Potential energy can be transformed to different types of energy, including kinetic energy. Activity 54 In Case You Missed It…

8. Energy is transformed when it changes from one type to another. ◦ Gravitational potential energy of the metal rod transformed into kinetic as it fell. Energy is transferred when it moved from one place to another ◦ When the metal rod fell onto the nail, it transferred kinetic energy to it, causing it to get pushed into the foam. Transferred/Transformed Energy

9. Prior Knowledge/Warm up Questions Complete the following: ◦ Activity A: Factors affecting GPE ◦ Activity B: Calculating GPE  OMIT #4 When finished, read the intro to Act. 56 on page D18 and write the definitions in your notes on an Act. 56 page. Potential Energy on Shelves Gizmo

10. Gravitational Potential Energy (GPE) = weight x height GPE= w x h What is the GPE of an object with a weight of 15 grams sitting at a height of 10 meters off the ground? Potential Energy on Shelves Gizmo

11. On a shelf that is 4 feet from the ground sits a book weighing 5 grams. On a shelf that is 6 feet from the ground sits another book that weighs 3 grams. Which book has the greatest GPE (in Joules)? Potential Energy on Shelves Gizmo

12. Please open your books to page D18 Activity 56: Shake the Shot

13. Heat- the movement of thermal energy from hot to cold. (pg D18) ◦ An object does not have “heat” ◦ Heat is the process of energy moving from a higher- temperature object to a lower-temperature object because of a temperature difference Activity 56: Shake the Shot

14. Temperature- a measure of the average energy per molecule of a substance. Activity 56: Shake the Shot Which beaker has a greater amount of thermal energy? More molecules= more heat/thermal energy 80 degrees

15. Focus : what different types of energy can kinetic energy transform into? Procedure step #1: Data chart on page D19 is in Content Library. Activity 56: Shake the Shot

16. Have your Unit D Anticipation Guides out, paper copy or OneNote. Statements #1 and #2: Anticipation Guide BeforeAfterStatement 1. An object does not have to be moving to have potential energy. 2. Only living things are associated with energy.

17. Read Activity 57 and complete notes sheet. Quiz on Wednesday over Activities 53-57. ◦ Not open notebook! ◦ You may use one side of a 3x5 index card with notes that you choose on it. Tonight’s Homework
