Science and Speed Related Question. Easy Points.

Suppose you are on an airplane moving at high speed. If you flip a coin straight up it will land in your lap rather than a great distance behind you.

Why does this happen?

THANKS!

Both you and the coin are moving at the same veloocity in the same direction. So just as flipping a coin straight up on the ground results in it coming directly back down regardless of the world both spinning and travelling around the sun at breakneck speed, the coin will also come directly back down in the flying aircraft!
Both you and the coin have the same momentum.

because the air in the cabin of the plane is moving the same speed as you, therefore not slowing it down. if you were standing on the wing of the plane, the coin would land behind you because it would hit all that air that isn't moving, in simple words... less friction due to air.
