The moon rotates once per revolution around the Earth, but that’s not a coincidence. Somehow the rotation and revolution are connected to each other. Some force is keeping them the same. How exactly does that work?

The other links and explainers are better resources, but for a fun discussion as far as I know: most bodies are very likely to end up tidally locked if they are close enough. For large moons, this can happen pretty early. For other systems, it could take so long that their suns will go supernova before that happens.
