* ''TabletopGame/Warhammer40K'': SpaceHulks are huge conglomerates of ships that are mushed together in the warp, occasionally getting spit back out into realspace and continuing to drift until they get sucked back in or fall into a sun.

** It may be a subversion, as ''Excelsior'' is in Earth's orbit. Her engines are no longer providing the thrust needed to achieve escape velocity, so she is losing momentum due to Earth's gravity.

Although that would open up a whole new can of worms in GravitySucks, as an orbiting object by definition can't be decelerated by gravity.

* In the game ''NexusTheJupiterIncident'' the earth designed vessels have huge thrusters on the back, and huge thrusters on the front. When you order you ship to stop, the ones in front fire like mad. In fact, you can clearly see a variety of maneuvering thrusters in operation. This is even true of the later alien vessel you get, which also has forward pointed engines (though far less obvious).

* Justified in ''Spelljammer''. Apart from working with [[AWizardDidIt magic]], the [[ExactlyWhatItSaysOnTheTin Space Ships]] have an emergency brake in the form of an array of rods that, once activated, are 'immovable' (they suddenly acquire tremendous inertia and thus act as very powerful anchors, decelerating the ship: notably, they're not ''truly'' immovable,'' since objects of infinite inertia would cause the ship to tear itself apart around them in an effort to reach zero speed instantaneously.)

** That's actually a potential aversion. Crichton presumably learned to fly in familiar Air Force fighter jets. Space combat would be extremely different to jet combat, regardless of what ''Star Wars'' shows us -- consider the Starfuries on ''Babylon 5'' and the way they coast, reverse, spin on their axes, and move ''nothing like any aircraft on Earth''. Just because Aeryn's ship can fly in an atmosphere doesn't mean she's going to be ''any good'' at it. When you have the capacity to raze entire cities to the ground from high orbit atmospheric dogfighting probably isn't high on your list of training priorities, and her atmospheric flying experience most likely consists of ship-to-surface and back again.

For that matter, the entire notion of only having enough fuel to travel so far is a little suspect: if you've got enough fuel to reach top speed, you've got enough fuel to go anywhere; once you reach top speed, you can just shut the engine off and coast, though this is assuming you're flying along a ballistic trajectory. Of course, it would become a problem if you [[ComingInHot don't have enough fuel to ''stop'' at the end]] -- or if, for whatever reason, you have to turn somewhere, or if your engine fuel doubles as power generator fuel, which would cause a black-out in your ship (which, if it comes up in a SpaceFriction plot, generally means the crew has a few hours to restore power before running out of air). Even so, this would result in a broken-engined ship perhaps missing its target or crashing into another, not stopping dead.

*** It wasn't unknown. It has to do with angular momentum and angular velocity. They were [[spoiler: swinging on the paracord, only very slowly after they got tangled and pulled a huge length of it father away from where it was caught, which acted like a pivot. Same principal of a ballerina slowing down in her spin by extending here arms outward. If one watches the scene again, you can see them still moving upwards in relation to the ISS. And with all of that equipment they have on, it makes sense as they why he was being pulled away. Which means it's still averted.]]

* The film ((Armegeddon}} references physics nicely when one of the NASA astronauts explains physics to our drilling team by pointing out that if she [[GroinAttack kicked one of them in the balls]], he'd float away. "Rock Hound" asks [[DeadpanSnarker when they start training for that.]]

* The dogfights in the ''Film/StarWars'' film series were [[WordOfGod intentionally]] choreographed around old WorldWarII dogfight footage, and thus visibly obeying this trope. The most noticeable application of SpaceFriction however occurs whenever a ship explodes in mid-flight: its explosion will be motionless despite whatever inertia the ship had previously. One instance where this can be seen very clearly is when the Y-Wings are making their trench run in close formation in ''Film/ANewHope''. One of the Y-Wings explodes, and the other Y-Wing suddenly leaps forward, leaving that explosion behind him.
