## 12/5 - 12/8

**M 12/5**

**T 12/6**

**W 12/7**

**Th 12/8**

### π΄ 2: T 12/6a, π‘ 4: M 12/5 - β©οΈ angular momentum lab (1)

Today, we'll start a lab in β©οΈ Pivot Interactives called "Marble Collides with Block and Can." In this lab, we will explore the **conservation of momentum and energy**. This lab is due in Pivot on Wednesday at 10pm.

**Homework**: Angular momentum problems are due to βοΈ Google Classroom by Monday, December 5th. β©οΈ Pivot Interactives lab "Marble Collides with Block and Can" due on Wednesday, December 7th at 10pm. *Reminder about Pivot - after the due date and time, you will not be able to work on the assignment and all work will be automatically submitted in Pivot. ***Unit Test on Rotation on Monday, December ****12*** th.* Remember, now that we're doing AP problems, it's a good idea to do as many of them as you can find. Start by looking on AP Central for the last 10 years of practice problems. There will be one or two rotation free response problems on every AP exam.

Watch the review videos on electric force and field:

Watch this video from Honors which reviews the concept of electric field. (optional)

Watch this video which reviews the vector nature and calculations for electric force and field, particularly superposition.

### β€οΈ 2: W 12/7, π 4: Th 12/8a - electric fields point charges (1)

~~Daily Check-in: superposition~~

Today, we'll tackle some problems on electric fields due to point charges from Chapter 22 (due Friday, December 9th at 10pm):

Required: 7, 8, 14, 15, 16-17, 19, 1981B3, 2006aB3

Enrichment: **Go on to problems below. **

**Homework**: If you need to review last night's video, make sure you do so.

### π 2: Th 12/8, π 4: Th 12/8b - electric fields point charges (2)

Today, we'll continue to do some problems involving multiple point charges. (Note that these are from the AP Physics B test. The C test questions will be more difficult, but this is a review of what you should have learned last year.)

Required: 2000E2 (a-b), 1975B2, 2002bB5, 2003bB4, 2006bB3

*You must do all of the parts of the problems which have to do with electric force and field, including the motion of a particle in the field. Parts that have to do with potential energy, work, or potential are optional for now, but if you finish early, then try to remember how to do these parts. *

**Homework**: * Unit Test on Rotation on Monday, December 12th.* Remember, now that we're doing AP problems, it's a good idea to do as many of them as you can find. Start by looking on AP Central for the last 10 years of practice problems. There will be one or two rotation free response problems on every AP exam.

Electrostatics problem sets 1 & 2 are both due to βοΈ Google Classroom Friday, December 9th at 10pm. If you need to review last night's video, make sure you do so. For next class (I recommend that you all watch this on Thursday evening), watch this video on calculating the electric field due to a continuous distribution of charge.
