The Starfuries use Newton's laws. They can flip around really fast,
whether they are moving or not (and it takes them the same energy),
because they have a low mass. Compared to a huge ship, anyway.

Yes, moving in space is much easier, because the only things you have to
worry about are mass and acceleration. No friction, drag, or anything
else. What I don't know how to explain is that the force required to
make a ship turn has nothing to do with whether the ship is "moving,"
both because that movement does not help or hinder the rotation, and
because this movement is relative to the point of reference you choose.

Now, if the ship is already rotating on its axis, we do have to consider
the conservation of angular momentum. That was not the original scenario.

Or we can talk about taxes. Or flarn.
