Is this on the MCAT? I remember it from my intro physics class, but it's not in Kaplan's books.

There was a question on the MCAT asking if something was in rotational or translational equilbrium.

You pretty much just need to know:

- the linear/2D kinematics principles/formulas
- a=v^2/r (rotational velocity), circumference, and other basic circle equations of the sort

Maybe I'm diverting a little.... simple answer - most angular and rotational stuff seems to be centered around torque and equilibrium.

i think most prep materials i've read say that rotational problems will be discussed in a passage. however, you might want to know the basics like rotational moment of inertia, m=(i)(alpha), and so on... .but i don't think you need to know many specifics to rotational motion.
however, like the last post mentioned, rotational equilibrium is fair game. however that follows the same rules and translational equilibrium (net force equals zero, constant velocity, etc)

based on my experience, you don't even have to memorize the equation. in terms of the rotational equilibrium, you should understand it and how it is different from the translational one. other than those easy equations that they expect you to memorize, the physical section of the mcat really tests you on the concept and your test taking skills. good luck.
