This week, we start with a midterm that will complete our work with linear and rotational systems. Then we will introduce components, angles, and trigonometry and spend the last three weeks reviewing the curriculum with the inclusion of angles. This is a great opportunity to improve conceptual knowledge.
For Tuesday,
We’ll spend 15 – 20 minutes preparing for the exam, 60 minutes taking the exam, 20 minutes reviewing the exam, and the rest of class doing some work with components.
Office hours on Wednesday is changed. NO OFFICE HOUR at 5:00 PM. Instead, I will have an office hour at noon on Wednesday. Come by and pick up your exam!

I found 5 old review questions and solutions kicking around. Please see: solutions to 1-4, #5
- See one way for Solving flywheel with hanging mass (this is really the worked solution to #5) (2 minutes)
- See a system of masses using work and friction (2 minutes)
- See a system of masses using dynamics (3.5 minutes)

Thursday: 2D mechanics (no trig).
First Hour, we look at components
Before class
- Do the MT#2 in fine form. The exam is posted on the main website.
- Please read through the problem set due next Tuesday before watching the videos so you know what you’re looking for. Do as much of the problem set as you can.
- Watch Intro Video to 2 Dimensions (3.8 minutes)
- See the video on estimating vector components (1.5 minutes)
- See the video on 2D Components of Force (8.5 minutes)
- See 2-D kinematics (3.5 minutes) Also see cool HS Website
In Class
- Review Midterm #2
- Practice Components
Second Hour
- See the video on 2D work (5 minutes)
- See this video about the mass on the inclined plane (9.5 minutes)
- See video on 2D momentum transfer (6.5 minutes)
In Class
- Talk about projects – Project proposal due by midnight this Saturday, Nov. 12.
- Practice slack lining?
