Re: Starship design revamping

[suggestion for defining agility as the amount of energy required to rotate
the ship about its axis at a certain rate]

Sorry, but rotating the ship, and changing course have nothing to do with
each other. Check the rules on plotting space combat in the old rules or grab a copy of MAYDAY. Both use correct physic in showing the result of course changes

If you are going "north" at 5 km/s, and you use the engines to give yourself
5 km/s of "east" velocity, you are now going "northeast" at 7.07 km/s! You have
to kill the "north" velocity and then add the "east" velocity if you want to
go "east". This could be done with one "burn", I *think* it would be a 7.07 km/s
burn applied in the "southeast" direction!!

Ain't physics fun?

ps. don't evenn *think* about arguing that the drives can get around this via
"magic" physics. This stuff is taking place in an area of physics where we
know what the loopholes are. (If you want "inertialess" drives, that's a
different matter, but don't forget to watch you intrinsic velocity!! :-)
