12th Grade Assembly - Disability Equity

We will all watch this equity presentation together.

Homework: Finish βž• Positive Physics work problems by Sunday at 10pm. Only completion score will count. No late work will be accepted.

🟩 6: T 1/25, 🟦 8: M 1/24 - βž• Positive Physics projectile motion problems (2)

Today, we'll finish the Projectile Motion Presentation by continuing to look at projectiles launched at an angle with more general projectile motion problems. We'll do Example 4 together.

Then, we'll continue practicing additional projectile motion problems. Do βž• Positive Physics "work" problems from unit 4: projectile motion:

  • complete problems 3

  • challenge

Homework: βž• Positive Physics problems above due Tuesday at 10pm. Only completion score will count, so keep trying the problems until you get them correct. No late work will be accepted. Unit Test on Dynamics in 2-Dimensions on Thursday, January 27th! (in marking period 2)

Optional Extra Practice: Chapter 3 #58, 60, 61, 65 (Solutions) and Projectile Motion CompuSheets page 2 (Solutions)

If you want more support with projectiles launched at an angle, you may watch the rest of Dan Fullerton's video on projectile motion (minute 11 until the end) and more practice problems below. If you like his videos, search for him on YouTube ("aplusphysics") for future topics. His "Regents Physics" series would be an appropriate level for this class.

Additionally, you can watch these more advanced videos on projectiles launched at angles and landing at a different height:

This video by Michel van Biezen is very similar to the problem that we did in class.

This is an even more complex problem from Flipping Physics. Try this on your own for more of a challenge.

πŸ’š 6: W 1/26, πŸ’™ 8: T 1/25 - βž• Positive Physics universal gravitation

Today, we'll talk about Newton's Law of Gravitation. We'll first look at Gravitational Interactions. Then, we'll introduce Newton's Gravitational Constant and do some calculations. Do βž• Positive Physics "work" problems from unit 11: universal gravitation:

  • gravitational force problems

Homework: Study for Unit Test on Dynamics in 2-Dimensions next class - Thursday, January 27th! (in marking period 2, includes everything we've studied through projectile motion, but not universal gravitation) Don't forget βž• Positive Physics problems from last time due Tuesday at 10pm. βž• Positive Physics unit 11 universal gravitation problems due Thursday at 10pm. Only completion score will count, so keep trying the problems until you get them correct. No late work will be accepted.
