In brief: See below
Vomitting is an automatic reaction by yiur brain to confusion about balance and position.
Balance requires at least 2 of 3 senses - visual cues, balance of otoliths (stones) in your middle ear, and proprioception (special sensory bodies in your nervous system).When you spin around, you mess up your visual cues and the otoliths.So your brain is confused about which way is which (e.g. Up vs. Down).
