π΄ 2: T 9/20a, π‘ 4: M 9/19 - Newton's Second Law problems (part 4)
Daily Check-In #2 : friction
We'll spend one more hour on Newton's Law Problem Set #1. 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
Check THIS POST or Google Classroom for Solutions and answers.
Homework: Finish working through required problems. βSummer Assignment Assessment on Thursday, September 22nd. Check THIS POST for exam topics.
π₯ 2: T 9/20b, π¨ 4: T 9/20 - circular & friction problems (1)
Daily Check-In #3: inclined plane
Today, after the daily quiz, you'll finish working on basic Newton's Laws problems from the last post, and then you will be working on some additional problems on more advanced Newton's Laws concepts from Chapter 6 in Halliday and one problem from Giancoli Chapter 5:
Support: 17, 25, 27, 35, 45, 70
Required: 23, 34, 51, 57, 58, 60, 68, 98, G42
Enrichment: 21*, 22, 25, 59, 103
* Requires calculus, skip if you haven't taken it yet.
I'll assess your understanding through conversations with you.
Homework: Make sure you've completed the first set of required problems. Continue with the problems from the post above. If you finished the required problems, move on to the banked turn problem in the next post.

β€οΈ 2: W 9/21, π 4: Th 9/22a - banked turns
Daily Check-in #4: circular motion
Today, we'll continue to work on the required problems on more advanced Newton's Law from Chapter 6 in Halliday and one problem from Giancoli Chapter 5:
Support: 17, 25, 27, 35, 45, 70
Required: 23, 34, 51, 57, 58, 60, 68, 98, G42
Enrichment: 21*, 22, 25, 59, 103
* Requires calculus, skip if you haven't taken it yet.
Then, with any time remaining, we'll try to figure out how fast we could go around the Bristol Motor Speedway in Nascar Problem. You'll learn about how to approach banked turn problems. We'll work in groups to try to figure it out.
Homework: Finish either the Nascar Problem OR the required problems from Ch 5/6. βSummer Assignment Assessment on Thursday, September 22nd.

Homework: In order to prepare for the lab we'll do early next week, watch the video below to review how to solve work/energy problems - Giancoli Chapter 8 #27. The important thing in this video is to make sure that you understand how to make a "before & after energy diagram." This method of solving energy problems is not something that is universal amongst physics teachers, but I do think that it is helpful and virtually foolproof, so I would like to see you use it. In addition, you should be able to use the conservation of energy equation to solve energy problems. This method is different than the "Work-Energy Principle" method, so you might want to also look that up in your textbook (p. 153 Halliday) and understand how it differs from the "conservation of energy" method. Both methods work, but given the situation, one usually works better than the other. Figure out why.
