🔴 2: F 9/15a, 🟡 4: W 9/13b, 🔵7: Th 9/14 - free body diagrams
I will be absent during the morning of Thursday, September 14th for period 4. During sub-study, please plan on studying for the upcoming review test. Use the summer assignment as a guide as to what you should know.
Daily Check-in #1: free body diagrams
Today, we'll do our first daily check-in. This will test your ability to apply the principles in the free body diagram video.
Homework: I want you to watch the second video tonight. Don't forget to take notes, pause, rewind, replay, or even fast forward if necessary. Come to class with any questions you have and be prepared for a daily check-in next class.
🟥 2: F 9/15b, 🟨 4: F 9/15, 🟦 7: F 9/15a - Newton's Second Law problems (part 1)
We'll continue to go through the solutions to the first Daily Check-in.
If there's time, we'll work independently and collaboratively on problems pertaining to Newton's Laws from Chapter 5 in our new Halliday textbook and Chapter 4 in our old Giancoli textbook (indicated with a G) starting at your level. I will assess your understanding individually and answer your questions as I circulate the room.
Support: 41, 48, 49, 51, 53, 56, 57
Required: 13, 56, 58, 64, G54, G55, G66, G75
Enrichment: 59, 67
Homework: Don't forget to watch the video above. Continue attempting and working through required problems. Commit to trying (or at least setting up) 2 problems.

Daily Check-In #2: Friction (7: M 9/18)
After a super brief daily check-in based on the friction video, we'll work independently and collaboratively on problems pertaining to Newton's Laws from Chapter 5 in our new Halliday textbook and Chapter 4 in our old Giancoli textbook (indicated with a G) starting at your level. I will assess your understanding individually and answer your questions as I circulate the room.
Support: 41, 48, 49, 51, 53, 56, 57
Required: 13, 56, 58, 64, G54, G55, G66, G75
Enrichment: 59, 67
Homework: Continue attempting and working through required problems. Commit to trying (or at least setting up) 2 problems. On a separate sheet of paper, write yourself a How-To Guide for Solving Newton's Law Problems. Include in that guide questions you would ask yourself while you are doing the problem.

Homework: Finish working through required problems.
If you have already tried Giancoli #54 and are stuck, check out my solution video below. (Please make sure you try this problem before you watch the video!) There are thinking steps missing in my video. Would you have known what to do? How did I know how to solve the problem this way? What strategies would you employ to get to this solution? These questions and possible strategies should be included in your How-To Guide.
If you can't work out the algebra on #55, don't worry about it. Below is the Solution to #55 so that you can get some assistance setting it up. (Click to enlarge) Try to figure out what generalizations you can make for yourself about how to tackle a hard problem like this. Make sure you are able to do all other required problems. Look through the problems, and make sure you understand them enough to present/make a video next class.
Giancoli Answers:
54. (m1 + m2 + m3)m2g / (m12 – m22)1/2
55. see picture above
66. a) (m2 - m1 sin θ) g / (m1 + m2)
b) a down (negative) requires m2 < m1 sin θ.
a up (positive) requires m2 > m1 sin θ
75. F = FT1 = FT2 = 1/2 Mg, FT3 = 3/2 Mg, FT4 = Mg
Additional Required Homework: Watch the two videos and answer the questions ✏️ in Google Classroom by Wednesday at 10pm:
Nascar Experience Driver View - Do not watch this whole video - skip to anywhere in the middle and watch at least one minute. Pay attention to going around curves. Audio doesn't matter.
Bobsleigh Speed Record - Watch this entire video
