I'd suggest looking at books on spacecraft mechanics.

One which may help is "Fundamentals of Astrodynamics" by Roger R. Bate, Donald D. Meuller, and Jerry E. White (published by Dover).  It's one of the better books on the subject, in my opinion, as I found it easier to read than many of the others I've seen.  One does need some familiarity with calculus and linear algebra in order to understand the theory, however, but it's not overwhelming.

Another one is "Modern Spacecraft Dynamics & Control" by Marshall H. Kaplan (published by John Wiley & Sons).  It's good, too, but I didn't find it as easy to go through as the other one.
