"Farther from gravity well" doesn't only explain it. You're talking about something like a bowling ball sitting on a trampoline, and orbit on the periphery of the depression , and like a wagon wheel, the part of spokes at the periphery move faster than the part of spokes near the hub. Again, that is varied acceleration.
Well, shoving as many analogies into one sentence as you possible can won't help explain it either. How about you give up?
