Honors Rotational Motion and Lab on Centrifugal Force

1) For Rotational Motion

know meaning of angular and tangential quantities and how they relate to each other. Such as Delta s =delta theta r; vtan = omega r; atan =alpha r, etc.
know relationship between Mac and centripetal force and ac = omega v= omega squared r = vtansquared/r know angular dynamics angular momentum = L = I omega;
Know I = M x [(r of mass) squared].
torque = I alpha just like F = Ma
more exactly
Delta L/Delta t = torque = Ftan x r ( r where Ftan is applied); just like Delta p/delta t = Fnet

Know if no alpha then no net torque so sum of torques = 0 [ cw - ccw +] choose axis to make equation easy to solve.
Know I = M x [(r of mass) squared].

KE rotational = I omega squared/2
KE total = 1/2 mv squared + I omega squared/2 squared; for rolling = vtan = omega r

Know angular kinematics , just like linear:
omega f = omega i + alpha delta t

Delta Theta = omega i delta t +1/2 alpha delta t squared
