Question

after getting down from the merry-go-round we lose our balance for a while .why?

Answer 1

This is a simple physical phenomenon.

Our ear keeps our balance by means of gel like fluids inside ear which also spins while we spin in merry go round.

So, while stepping down this spinning activity of the fluid persists for some time and causes our imbalance.

Due to the fast rotation of the carousel, our body is unable to maintain balance and gets slightly disoriented.
