Physics 2210 Preflight 15


Closed. Preflights are due at 10 AM on Tuesdays.


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.


    Thanks for your time.
