Document Summary
Hw #5 solutions are already posted there"s a short hw #6 due on wed night . Don"t forget about the review/hw session today between 5:30 7:00 (ta), 7:15 8:45 (si: test #2 when: tomorrow. 7- 9; 6 question/ problems with multiple sections (3 will be multiple choice) similar format to rst exam. Energy associated with state of rotational motion? rotational inertia (moment of inertia) about some axis of rotation. For a discrete number of particles distributed about an axis of rotation. 2 m r i i all mass units of kg m2. Rotational inertia (moment of inertia) only valid about some axis of rotation. For arbitrary shape, each different axis has a different moment of inertia (r"s are different). I relates how the mass of a rotating body is is distributed about a given axis. (t) d dt v = d dt r = r v = r.
