AT Cycle 15
12/6 - 12/9
🔴❗ 1: M 12/6, 🟡❗ 3: M 12/6 - Rotation Assessment
Rotation Assessment TODAY!
Homework: 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.
🟥 1: W 12/8 lab, 🟨 3: T 12/7 lab - electric fields point charges
Daily Check-in: superposition
Today, we'll tackle some problems on electric fields due to point charges from Chapter 22:
Then, we'll continue to do some problems involving multiple point charges during the second hour. (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.)
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: If you need to review last night's video, make sure you do so. Then watch this video on calculating the electric field due to a continuous distribution of charge.
❤️ 1: Th 12/9, 💛 3: W 12/8 - continuous charge distribution (1)
Daily Check-in: E-field continuous distribution
Today, we'll do some problems which require us to calculate the electric field due to a continuous distribution of charge:
Required: Electric field integrals #2 only (WHERE you put theta matters in what the integral looks like, but the result should be the same if you've chosen the correct limits. Here's one solution, and here's another, and here's yet another), 1981E2, redo Giancoli Example 21-10 (p. 559), and state why the book chose to solve with d(theta) rather than dy. Also, Halliday Chapter 22 #28, 29, 32, 31
Enrichment: Halliday Chapter 22 #24, 33, 65
Homework: By Monday, read this page on Electric Field Lines from The Physics Classroom. Make sure that you understand the rules for drawing electric field lines.
