Clearly in a galaxy far, far away the laws of physics are a bit different. As physics often are in space opera. I guess in Star Wars space is filled with ether, not vaccuum. And ether, despite being a rarefied element, somehow impedes motion. It does explain why X-wings have an etheric rudder. |

Actually, IIRC, the working theory on that is that what we see as forward motion is actually acceleration. If ship A and ship B are moving forward at a Space of 8, and ship B is hit by an ion cannon, its drives cut out. It is still moving forward at a Space of 8 (objects in motion and all that), but ship A is continuing to accelerate forward at Space 8, putting 8 units between it and ship B, which appears to have come to a complete halt, depending on the POV. In ESB, the ISD is accelerating forward at a constant rate, but is then hit by an ion cannon shot and disabled. The ISD's engines fail, and to an observer, it appears that the ship is slowing down, when it is actually just no longer accelerating. _________________ "No set of rules can cover every situation.

Otherwise if A is actually an observer on the planet Hoth (effectively stationary with respect to Ship B's starting position). Ship B (the ISD) will not appear to stop moving. It will just move forward at the same accumulated velocity (First Law and all). But then I am of the opinion that spending much time attempting to rationalize the behavior of ships in Star Wars with real physics is time that could be better spent rewatching the movies, playing the RPG, drinking beer, or doing any number of other things.
Also, having ion weapons effect the engines makes sense to me and to my mind requires no justification other than a cursory reasonableness test. |

I can agree with that. 8) _________________ "No set of rules can cover every situation. It's expected that you will make up new rules to suit the needs of your game." - The Star Wars Roleplaying Game, 2R&E, pg. 69, WEG, 1996.
