The Short question here is do teleportation spells in Pathfinder/3.5 carry over any kinetic momentum you were subject to before the teleportation. For context, please see this example situation (which will become a real situation depending on the answer):
Bob "This is a hypothetical situation" Hrothbert has just found himself pushed over a cliff. The cliff is high enough that he does not hit the ground after a single round, so is free-falling. Poor Bob did not prepare Feather Fall today, so he can't save himself that way, but he did prepare Dimension Door! Bob readies to cast this spell before he hits the ground, and just before he dimension doors himself to a nearby rock.
Does he A: Safely land on the rock, the kinetic energy having dissipated when he cast the Dimension Door spell
Does he B: Take terminal velocity falling damage as he hits his new location just as fast as when he had teleported?
