Ok, I should probably know the answer to this, but I can't convince myself that I do. Anyways, when a rocket is in space, will it accelerate as long as the engine is firing, or will it reach a terminal velocity.
For example. Lets assume that the thrust leaves the engine at 1000 m/s. Is the rocket's top speed 1000 m/s, or will it continue to accelerate as long as the engine is running?
