When a rocket in outer space runs out of fuel, its velocity decreases due to a lack of propulsion.
When a rocket ship accelerating in outer space runs out of fuel, the velocity does not remain the same or keep increasing; instead, it decreases. This decrease in velocity occurs because once the fuel is depleted, there is no longer a force propelling the rocket forward to counteract the effects of inertia and gravity. As the remaining fuel is burned, the rocket's mass decreases, leading to a decrease in acceleration and ultimately velocity.
