I'm at the end of a 1st semester college Physics class. I was handling it pretty well until we got to Rotational Dynamics/Angular Momentum. I could and will probably survive by practicing problems and recognizing the mechanical steps required to solve these certain types of problems, but I really want to acquire a fundamental understanding of the concepts involved rather than just be able to repeat the steps required. Can anyone recommend some good, clear, easy to understand reading on these topics? Thanks.
