In principle, yes. That's called inertial navigation and while it works, for a while, the errors involved are big enough that without a feedback loop you'll be happy if it lands anywhere near the target area. And with the size of the payloads of the day 'near' isn't nearly precise enough. So these were only usable as a terror weapon. Unfortunately, not much seems to have changed in 80 years in spite of our ability to target much more precisely.
