Today we talked a bit about air resistance (drag), terminal velocity, and then moved on to interacting objects. We also reviewed Newton's 3rd Law a bit. Tomorrow we will review for the Test on Thursday.
Friday we looked at solving problems involving ropes and pulleys. We began an example and did not finish before the bell rang. I've created a video (two actually) to show how to solve the problem in two different ways. You should use whichever way works best for you.
Video 1 - solution using a system of equations Video 2 - shortcut solution |
Reminders:
Chapter 2 test retake is Wednesday 10/17. You can take the retest either before school or after school, but you must complete all of the Chapter 2 homework (75% completion on each assignment) to be eligible for a retake!
