[QUOTE="Achan hiArusa, post: 8818782, member: 2597"] That first sentence just hurt my Physics teacher soul. There is no mass change to the ships so inertia is constant since inertia [B][SIZE=7]∝[/SIZE][/B][SIZE=4]mass. So much so, in fact, they are considered the same thing. And speed is not conserved, but momentum (mass x velocity) is. You are also confusing speed with velocity and they are different. If it is moving at a constant velocity it is an inertial reference frame and no forces are acting on it. And by the principles of relative motion a force enacted on it at 0 mph will have the same effect as when it is moving 1,000 mph. The problem is when you apply a positive or negative acceleration while trying to turn at the same time. It is when you deal with gravity and media does velocity make a difference because maintaining a constant velocity means having to balance the force of thrust with the force of friction and gravity.[/SIZE] [/QUOTE]
