Quizplus · Accepted Answer

In outer space, there is no air resistance or friction to slow down the rocket ship. Therefore, once the rocket ship runs out of fuel, it will continue to move forward at a constant velocity due to the principle of inertia. It will not gain any more speed because there is no force acting on it.
