AT Cycle 4

🔴 1: Th 9/24, 🟡 3: Th 9/24a advanced Newton's Laws

Daily Check-In: Inclined plane

Today, we'll continue what we were doing yesterday and finish at least the required problems 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, if you haven't completed it already, 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: Continue either working on the Nascar Problem or any required problems from Ch 5. We'll have one more class period to finish these.

Homework: Finish the Nascar Problem and any required problems from Ch 5. Then, 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.

❤️ 1: T 9/29a, 💛 3: T 9/29 energy lab

Today, we'll do a lab in Pivot Interactives called "Stopping Distance (Scaffolded) BCF." The goals of the labs are:

• Review how to perform conservation of energy problems.

• Review how to linearize graphs and find unknown values from mathematical relationships.

• Familiarize yourself with Pivot Interactives as an online lab tool.

You'll work collaboratively this hour to try to complete this online lab. In typing your answers in Pivot Interactives, you might find it helpful to insert formulas in your responses. Learn how to do that in Pivot Interactives HERE.

📕 1: T 9/29b, 📒❗ 3: W 9/30 energy review problems

Today, we'll start by finishing the Pivot Interactives lab "Stopping Distance (Scaffolded) BCF."

Then, we'll the following problems from Chapters 7 and 8 in Halliday to review energy problems from last year. If you haven't watched the videos from last night, do that first, and follow the steps for making a "before and after diagram" for every energy conservation problem.

Support: Ch 7 #32, 36, 45; Ch 8 #19, 21, 36, 52, 55
Required: Ch 7 #30,54, 62, 65; Ch 8 #30, 34, 56, 57, 63, 91
Enrichment: Ch 7 #79; Ch 8 #33, 35, 75, 78

We'll continue on this set next class.
