🔴❗ 2: W 9/18, 🟡❗ 4: W 9/18, 🔵❗ 8: W 9/18 - summer enrichment review

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

Homework:  Remember to answer the circular motion questions ✏️ in Google Classroom by Wednesday at 10pm.❗Summer Assessment on Tuesday, September 24th. ❗Assessment on Chapters 5 and 6 in Halliday plus banked turns on Monday, September 30th.  

🟥 2: F 9/20 lab, 🟨 4: Th 9/19 lab, 🟦 8: Th 9/19 lab - 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:  I recommend you finish the Nascar Problem AND the required problems from Ch 5/6.  ❗Assessment on Chapters 5 and 6 in Halliday plus banked turns on Monday, September 30th.  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.

❤️ 2: M 9/23, 💛 4: F 9/20, 💙8: F 9/20 - energy conservation

Daily Check-in #5: Energy Conservation

With whatever time is remaining after the check-in, we'll start the 📓 conservation of energy lab.  

We'll continue review of last year's material by doing a lab with energy. You'll need to find the coefficient of kinetic friction between a wooden block and the lab table. The only measurement devices are a meter stick and a balance. You cannot use any timing devices or motion sensors.  You'll focus on work lost to a non-conservative force.  

Homework: Have a plan for how you will complete the conservation of energy lab.  ❗Study for Summer Assessment next class - Tuesday, September 24th.
