Spring 17 Mechanics Week 8

Monday

In Class

  • Talk about projects – Project proposal due by this Wednesday.
  • Practice slack lining?
  • Mistake I made with pulling string on wheel?

After Class


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

  • 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.
