# Earth rotation with atmosphere

Note: This might be a very dumb question

Considering Earth's rotation on its axis, I was thinking it made sense for the outer sides of the Earth to have a significantly higher tangential speed, considering how the radius is much larger, in order to keep the same rotational speed.

Having considered this, the question I was posing myself was: If you were to jump perfectly up, so no force is applied by you in the x-axis, since the atmosphere would have a slightly higher speed, would you fall slightly further away from where you jumped?

• In fact you would fall back because you are slower than the atmosphere. But this would also happen without atmosphere. Check out Coriolis-Force. The derivation of that is simple – Finn Eggers Apr 24 at 13:43
