W15 Mechanics Week 5

Week 5: Energy diagrams, Universal Gravity, 2-D kinematics


Day 1: 2D mechanics (no trig).

Thanks for your feedback on Thursday. Please see summary and my response on the main class website.

Before class

  • Do PS #4, on main website – First Question is Revision of MT#1 (answers and comments are posted on main website)
  • It is a good idea to read through the problem set before seeing the videos so you know where the information is to lead you. It is also a good idea to review parts of the videos if you need to check on something while doing the problem set.
  • See the video on 2D work
  • See video on 2D momentum transfer
  • This video is due for Tuesday, but if you can, see it now on estimating vector components

In Class

  • Hand in PS #4
  • Talk about projects – Project proposal due by midnight Saturday, Oct 24.

After Class


Day 2: (Inclined Plane)
