Question

While stopping after spinning for sometime, a person loses his balance, Why? ​

Answer 1

It disorientates them and cause the brain to lose oxygen so you get dizzy

Answer 2

When you spin around rapidly, that liquid in the inner ear spins as well. When you stop spinning the liquid keeps moving for a bit, confusing your brain into thinking that you're still spinning even when you're standing still - and that makes you feel dizzy.
