"What will happen if Earth stopped rotating?" have been answered multiple times with a lot of informative and interesting answers. Continuing this hypothetical question, I have another one in mind.
If Earth stopped, how will it start rotating again? I've read that Gravity assist/pull from other planets and Moon will make Earth start rotating again. I would like to know what else can play a role in Earth's re-rotation.
I will also appreciate if you could help me know how much time would it take to Earth regain its rotating speed.
Edit1: This is clearly a curious question from a made up situation. I am quite familiar with the fact that Earth can't and won't stop rotating. It's just a fictional question coming in mind after reading the similar topic "What will happen if Earth stopped rotating?".
Edit2: Earth's course around the sun is called Revolution. The day and night cycle is the result of Earth's rotation. That's what I'm curious about. I only want to know the factors that will make Earth "Rotate" again and I haven't considered anything related to Revolution.
I'm sorry I wasn't able to make myself clear. Please let me know if we still need some more clarifications.
