The reading assignment for this week would be to finish our lecture notes labeled "Noninertial", and Taylor 9.3 and 9.5 (you can read other sections of 9 if you want the background, but it's not obligatory)


  1. Go back to Taylor Chapter 1, page 29, and look once more at Eq 1.48. We talked about that one a lot early in the semester (and revisited it on a recent homework.) Let's apply it - You are near the outer edge of a spinning merry go round. If it spins with constant angular velocity, which of the 4 terms (mr'', -m r phi'^2, m r phi'', and 2 m r' phi') are ZERO? (Briefly, why?)



  2. If you are now walking from the edge towards the center of that same merry go round,which of the 4 terms (mr'', -m r phi'^2, m r phi'', and 2 m r' phi') are ZERO? (Briefly, why?)




  3. In your own words, explain what "centrifugal force" and "coriolis force" mean. When do you feel them (in real life)?





  4. Please submit a question you have about anything at all from material you are studying for the final in this course!
    Note: Our final exam is in a week - Tuesday, May 3, 7:30 PM.
