How much/what physics do I need to know to be prepared for physical chemistry course in quantum mechanics?

[Corribus]

You won't need much in the way of formal physics outside of being familiar with concepts like angular momentum, forces, energy and so forth. Strong math background is much more important, particularly working knowledge of vectors, multivariable calculus, polar coordinates and (bonus) differential equations or linear algebra. Most pchem courses include instruction in these areas where necessary but you'll struggle less if you already know how to do a lot of that stuff.

I agree with Corribus.  The only thing that I would add is that one should have a positive attitude about learning new mathematics, or at least one should not let unfamiliar mathematical concepts become a barrier to learning.
