F15 Mechanics Week 7

Day 1:

Before Class

  • Watch an introduction to simple systems This is an important video to understand systems.
  • Your text doesn’t address dynamic systems, so please read the information on this website: Atwood Machine by individual masses
  • Solutions to BE#4 have been posted on the main web page. Please see them.
  • PS#6 is due today. Because the videos address the new material, and PS#6 material is from videos and discussions last week, I’d like to collect PS#6 at the beginning of class, and concentrate on systems.
  • PS#7 is posted and is due Wednesday.

In Class

  • Tug-O-War

After Class

After Class

  • Problem Set #7 due today.
  • Prepare for MT2: Did you look at MT2 from years past? Remember you have access to all past classes through http://sharedcurriculum.wikispaces.com/ but NOTE! last winter, I didn’t cover centripetal acceleration until after the second midterm. So you won’t see these kinds of questions on MT#2 from W2015, but you should expect one this quarter.


Day 4: Midterm #2.

Before Class

  • Did you prepare your formula sheet?
  • Test yourself without the answers?
  • Teach the stuff you’re not sure of to someone else?

During Class

  • Midterm!
