Today, you may collaborate in order to review any of the topics from the summer assignment.ย Topics for this review assessment can be found here.ย ย

Homework:ย Remember to answer the circular motion questions โ๏ธ in Google Classroom by Wednesday at 10pm.โSummer Assignment Assessment on Thursday, September 22nd.ย ย

### ๐ฅโ 2: Th 9/21b, ๐จโ 4: Th 9/21, ๐ฆโ7: Th 9/21a - review assessment

โSummer Assignment Assessment TODAY!ย ย

Homework:ย Make sure you've completed the circular motion questions in Google Classroom, and look through the required problems in the next post. โAssessment on Chapters 5 and 6 in Halliday plus banked turns on Thursday, September 28th.ย ย

### โค๏ธ 2: F 9/22, ๐ 4: T 9/26a, ๐7: Th 9/21b - 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:ย Make sure you've completed the first set of required problems.ย Continue with the problems from the post above.ย If you finished the required problems, move on to the circular motion problems in the next post.ย โAssessment on Chapters 5 and 6 in Halliday plus banked turns on Thursday, September 28th.ย ย

### ๐ 2: T 9/26, ๐ 4: T 9/26b, ๐7: F 9/22 - banked turns

Daily Check-in #4: circular motion

Today, we'll continue to work on the required problems on more advanced Newton's Lawย 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.ย You'll learn about how to approach banked turn problems.ย We'll work in groups to try to figure it out.ย ย

Homework:ย I recommend you finish the Nascar Problem AND the required problems from Ch 5/6.ย Next class, you'll have time to complete what you have not already if there's anything, but it'd be better if you used that time to practice. ย ย โAssessment on Chapters 5 and 6 in Halliday plus banked turns on Thursday, September 28th.ย In order to prepare for the lab we'll do by the end of the week, watch the video below to review how to solve work/energy problems - Giancoli Chapter 8 #27.ย The important thing in this video is to make sure that you understand how to make a "before & after energy diagram."ย 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.ย In addition, you should be able to use the conservation of energy equation to solve energy problems.ย 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.ย Both methods work, but given the situation, one usually works better than the other.ย Figure out why.

For those of you who are curious, watch the video below about the dot product:ย
