You know, the really funny thing is that when we did the tutorial for this, I could do everything. I really got this topic. And now I don't understand a thing. It's not even like I didn't listen in lecture, this is like one of the few physics topics (topics in general, actually) that I paid attention.
Anyway.
Gravitational Potential = -GM/r
Gravitational Potential Energy = -GMm/r
Gravitational field strength = GM/r^2 = F/m
angular velocity, w = 2pi/T
tangential velocity, v = rw
centripetal acceleration, a = rw^2 = v^2/r = vw
centripetal force, F = ma = mv^2/r = mrw^2
Yay! Now to launch a satellite into orbit.
