To start off with the first question,How would a space ship do yaw,pitch or roll in zero gravity (as in non orbital zones)?
Dear Jim,As far as i know ( and i know just about nothing) flywheel or reaction wheels are for very small changes in angular momentum.By an spaceship rotation i ment more like how a plane rotates, well that is if "future" spaceships would rotate in that manner at all.Maybe my ideas are flawed because they are mixed a bit with scenes seen in movies. Never the less, kindly explain a bit more on this matter.one more thing, does the reaction wheel use the "action/reaction" law to rotate?
