Did you complete the reading assignment? (Typically this means at least 20-30
minutes looking over the assigned sections of the book.)
☐ yes
☐ no
Moment of inertia is biggest for:
☐ compact objects
☐ objects that are spread out
☐ neither; doesn’t depend on shape
Angular
acceleration will definitely increase if:
☐ torque is decreased and momentum of inertia is
decreased
☐ torque is decreased and momentum of inertia is
increased
☐ torque is increased and momentum of inertia is
decreased
☐ torque is increased and momentum of inertia is
increased
Compare a ball rolling down a ramp (with
no slipping) with a block sliding down another ramp at the same angle (with no friction). Which one
will reach the bottom first?
☐ the ball
☐ the block
☐ same time
Ralph heard his instructor say "Moment of inertia plays the same role in
rotational motion that mass does in linear motion." This confuses him. In your own words, explain
to Ralph what that means. (I don't want
equations. I just want a short conceptual explanation.)
The comments in the next next two boxes go into a big, mostly anonymous text file that I skim through before the morning lecture, using the comments to help me plan class discussion. ("Mostly anonymous", because I can track down who made what comment, but it takes some effort on my part to do so.) Therefore, if you really want to make sure I see your question/comment and answer it individually, you should send it to me via email and not through this form.
Which part of today's assignment was particularly hard or confusing? What
would you like to spend extra time on in class?
