Hey there SmoothCat! Welcome to PF!

If a body is spinning around the z - axis and an element of that body detaches on its own and flies off tangentially, does the rest of the remaining rotating body experience a change in angular velocity???

Please only send me a reply to this question if your willing to give me somewhat of a detailed response, because I'm really struggling with this idea...
If it flies off at the same speed as its tangential speed just before so its angular momentum (about the centre) stays the same then no, there's no change in angular velocity of the rest.

That's because if the angular momentum of the detached part stays the same, then so must the angular momentum of the rest.

(I'm sorry, but any more detailed response would be superfluous! )
