Fall 2016 Mechanics Week 9

This week we continue exploring vector components and how we can decompose them into perpendicular components. We look at the Conical Pendulum… or Tetherball problem, and we look at how a point mass can have angular momentum.

For Tuesday,

first hour, we look at how a point mass (radius = 0) can have angular momentum

Practice problems.
Plan video project. Proposed video projects should be posted by Tuesday night, Nov. 15.

For Thursday, under construction below this line. Please ignore until later today (Tuesday)

first hour,
Before Class

  • I posted rather complete solutions for MT#2 and Solutions to PS#7 on the main class website. I spent several hours on it, so please take a look and tell me if my efforts were worth it.
  • Please see the video on angular momentum: Wheel Kick and Angular Momentum
  • Veritassium Which Block Goes Higher?
  • See this short video on Angular Momentum and Figure Skating
  • Solutions to MT#2 posted on main website, PS#8 solutions posted on main website. Please make sure as soon as possible that you would get all these problems correct if you were to encounter them again.

In Class

  • Big Exam #7

After Class

  • Please read and try the problems on PS#8 posted on main website

second hour,
Before Class

  • See video on Slack Lining. Is this how you solved the problem?
  • Watch Statics and do problem #1 on PS #8.
  • There’s a small amount of new material today, so please take a look at the solutions I posted for MT#2 and Solutions to PS#7 on the main class website. I spent several hours on it, so please take a look and tell me if my efforts were worth it.
