eli5 What would happen if I had a big enough airplane to throw a ball around then the airplane turns while the ball is in mid air?

Only *changes* in speed or direction would be noticeable.
Think about that fly buzzing around in the car while we’re driving. Flies can’t fly 60mph, right? He flies normally because inside of the the car, he is part of the car. But, if we slammed on the breaks really really hard, the fly would move towards the windshield, and so would you. That is why we have seatbelts 🙂
I one time tried to jump really really high, so high that the Earth would keep spinning under me and I would land in a different place. But I landed in the same spot. Better idea, I tried to throw a rock super high. But it came straight down too.
It turns out the earth is our car and we are like the flies!
