π΄β 1: M 4/26, π‘β 3: M 4/26a LR circuits revisited & website review
π΄β 1: M 4/26, π‘β 3: M 4/26a LR circuits revisited & website review
Today, we'll revisit the LR circuits quiz. We will do a β GoFormative re-assessment which will count for a grade.
Then, we'll take some time to look through the website, evaluate the work on two different pages, and make suggestions for improvement. See βοΈ Google Classroom for the form. Then, by Sunday at 10pm, make revisions to your webpage if needed.

Homework: Give your website feedback by Wednesday at 10pm. Make webpage revisions by Sunday at 10pm.
π₯ 1: T* 4/27, π¨ 3: M 4/26a heavy rope problems
π₯ 1: T* 4/27, π¨ 3: M 4/26a heavy rope problems
Today, we'll do some AP Problems that involve the concept of heavy ropes.
Make sure all the problems up to this point are complete.
Homework: QUIZ Wednesday on velocity dependent forces. Heavy Rope Problems due to βοΈ Google Classroom by Thursday at 10pm.
Watch the following video on universal gravitation. If you remember how to use the formula for the force of gravity, skip the first 3:27, and focus on the calculation of gravitational field. As you're watching this video, relate it to what you know about electric fields and Gauss's Law.
β€οΈβ 1: W 4/28a, πβ 3: W 4/28 gravitational field
β€οΈβ 1: W 4/28a, πβ 3: W 4/28 gravitational field
QUIZ Today on velocity dependent forces.
After the quiz, we'll start with a brief discussion about potential energy versus position graphs. We'll use a physical analogy of a hill as a model of how to think about these types of problems. This discussion will help you solve the last problem in the required set below.
Then, we'll take a look at some problems involving gravitational field:
Required: 2001M2, 1999M2, 1995M2 (only peripherally related, but good to know about potential energy)
Homework: Gravitational Field problems due to βοΈ Google Classroom Friday. Watch the following video on Kepler's Laws:
π 1: W 4/28b, π 3: Th 4/29 orbits
π 1: W 4/28b, π 3: Th 4/29 orbits
Today, start by finishing any problems from last time.
Then, you'll work on the following AP problems to check your understanding of Kepler's Laws.
If you're wondering why 1994M3 part d has two correct answers that seem totally different, check out this article:
Homework: Gravitational Field problems due to βοΈ Google Classroom Friday. Orbit Problems due to βοΈ Google Classroom on Sunday at 10pm. Don't forget to also make modifications to your E&M website by Tuesday at 10pm.
Watch the following video on simple harmonic motion (SHM):
Check out this video for a better understanding of "angular frequency" Ο (aka frequency of oscillation) and how it relates to the angular speed Ο we already studied in rotation:
