ok...
There are two basic types of movement/propulsion that I'm familiar with:
- Newtonian
- Inertialess
Intertialess is what we see in Star Wars, Star Trek, even Firefly/Serenity. Ships instantly jump to whatever speed they want, or come to a sudden stop (almost like taking foot off the gas on a car). They bank like aircraft flying in an atmosphere and such.
Newtonian - well aircraft work just fine in atmo, and again that is what has been copied for sooo many scifi shows, movies, books. Aircraft use thrust, lift, weight, drag. They can't fly backwards because the wings don't work that way, they can't come to a stop because thrust pushing the plane forward creates lift over the wings, etc (en.wikipedia.org/wiki/Lift_(force))
(looking now at again, B5 and BSG-2nd version) But in space, we don't have that gravitational pull to fight against, no atmo to create lift over wings. If you are traveling on a vector (direction) and wish to make a right turn (90 degrees) you turn the craft (with thrusters) and change the direction of your thrust, which will cause a change in the vector of your speed eventually you are traveling the direction you want to go.
well, if we were using Newtonian physics yes, we could hit the maneuvering thrusters, flip over, fire backwards while our engines actually slowed us down. Go watch the original pilot/miniseries for the newer BSG from SciFi. There is a scene where Apollo and Starbuck do just that.

Why, do you need this clarification, because an overtly smart player will turn his fighter facing backwards while traveling in a direction (space movement don't you know) and then the tailing fighter now has a head to head situation but will have difficulty catching the lead fighter besides being shot at with all the lead figthers weapons.
this is a more complicated version of what I was talking about - using weapons that could fire to the rear to shoot at a tailing enemy fighter - and was solidly told I was basically an idiot for considering it. The "powers who wish to be" have spoken that a fighter may "not" fire back at a trailing enemy.
