4. Unit 1, Day 10 Quiz • Shhhhh: If students from later periods walk in and say that they heard there wasn’t a “real” quiz, you will have double the quizzes on Mon/Tue!

5. Announcements • Friday, February 7th – Girls Soccer Game…The Rematch! • Heal the Bay Bring lunch with you, we won’t be until 2pm

6. Reflect on M/T’s Quiz • Based on your score, does this change any ofyour numbers in your learning log (2/5 or 2/6)? • Knowledge Targets: #13, #14, #15 • Reasoning Targets: H, I • 5: No Idea • 6: Heard it before • 7: Recall definition • 8: Recall definition & simple calculations • 9: Total beast

7. Ensure booklet is finished • There are inserts for each of the LECTURES posted on my DP: dp.davincischools.org/staff/blarkin • Staple or tape them in if you are missing notes or cannot read your notes • Remember, this will be used for SLCs and POLs. I expect to see completed packets! (That means lectures AND videos)

8. Calculator • Bring a calculator to the exam • Phones will not be allowed • You have until next week to ensure you have a calculator • You must be able to square AND square root numbers

9. Review • Go through the packet • We will work on problems #1-10 today • There is paper on your table for scratch work, but do not lose the papers, otherwise you won’t have them for study materials. Alternatively, you can write in a notebook.

10. Review • Momentum – EasyIf a 2kg object is moving at 4m/s, what is its momentum?

11. Review • Momentum – DifficultIf a 2kg object has a momentum of 10kg*m/s, what is its velocity?

12. Review • Momentum – DifficultIf an object has a momentum of 15kg*m/s and is moving at 3m/s, what is its mass?

13. Review • Impulse – EasyYou impact a wall with a force of 2N. It takes 3s to complete the impact. What is your impulse?

14. Review • Impulse – DifficultYou run into a wall and have an impulse of 16 kg*m/s. If you feel 4N of force, how long did it take to complete the impact?

15. Review • Impulse – DifficultYou run into a wall and have an impulse of 16 kg*m/s. If you take 2s to complete the impact, what force do you feel?

16. Review • Impulse-Momentum Theorem – DifficultAn airbag stops you in a collision in 2 seconds. You are 55kg heavy and you were driving at 20m/s. What is the force you will feel?

17. Review • Momentum in an Elastic Collision – DifficultA 12kg billiard ball rolls to the right at 1m/s and hits a 4kg billiard ball that is at rest. They bounce off without deforming. After the collision, the 12kg billiard ball continues to move to the right at 0.5m/s. What is the 4kg billiard ball’s final velocity AFTER collision?

18. Review • Momentum in a Perfectly Inelastic Collision – DifficultA 12kg clay ball rolls to the right at 1m/s to hit and stick to a 4kg clay ball that is at rest. What is the velocity of the combined clay ball AFTER collision?

19. Review • Momentum in an Explosion – DifficultA 1.5kg cannon is loaded with a 0.06kg ball (total mass is 1.56kg). The apparatus is at rest. The cannon is ignited and launches the 0.06kg ball forward at 75m/s. What is the velocity of the cart following the explosion?

20. Learning Log Update • Based on today’s review, does this change any ofyour numbers in your learning log (2/5 or 2/6)? • Knowledge Targets: #1, 2, 3 • Reasoning Targets: A, B, C, D • 5: No Idea • 6: Heard it before • 7: Recall definition • 8: Recall definition & simple calculations • 9: Total beast

21. Break

22. Your Task: Review • We went over the math equations together • Tomorrow we will do questions 12-23 (W, E, and P) • It is YOUR responsibility to do the vocab • Found in notes or videos • It is YOUR responsibility to do the conceptual questions • Found in notes or videos

23. Speech • For your RG, you must give a three minute speech • Each person should speak for one minute each (assuming you have three group members) • Parts of the speech • How does your rube goldberg decoration represent your topic? • What are three facts about your topic? • What is a possible solution to your topic? • How does your final step represent your topic? • Where do you see kinetic energy? • Where do you see potential energy? • Where do you see conversion of energy?

24. Calendar Before End of Unit One • Class 1: 2/3 or 2/4  Topic = Power, Project = Building • Class 2: 2/5 or 2/6 Topic = Review, Project = Building & Speech • Field Trip on Friday, 2/7 • Class 3: 2/10 or 2/11 Topic = Review, Project = Building & Speech • Class 4: 2/12 or 2/13 Unit One Exam • No School on Friday, 2/14 • No School on Monday, 2/17 • Class 5: 2/18 or 2/19 Project Presentations
