Coin falling from an airplane?
Hey,
quick question…
If you drop a coin from a fast-flying airplane etc., where does it land?
Slightly against the direction of flight, directly below me or more in the direction of flight + why?
I'm not sure, I think it's a bit against the direction of flight, but would that be consistent with the law of inertia?
Would be great if you could help me..

What do you think the coin is moving in this direction?
Do you mean “just under the place where I left the coin off” or “just under the place where I am when the coin lands”? Because your plane’s going on. Until the coin arrives on the ground, you have already put a few kilometers back.

Simple consideration: The coin first has the same speed and direction of flight as the aircraft. This means that it does not fall down vertically, but also “climbs”. This part is the inertia.
However, the coin is braked by the air resistance. In other words, it does not remain as fast as the plane in the horizontal direction, but it becomes slower and slower until it falls at some point vertically downward.
Of course, depending on the direction, the coin can also be moved laterally from the wind, or it flies a bit further, or it is braked faster.
However, the falling distance would have to be quite long that a counterwind of my 50 km/h will blow the coin back over the entire route, which it has left out of the plane at the beginning of 800 km/h. I therefore believe that a “against the direction of flight” is only conceivable under special circumstances (strong wind, long falling distance).
Thank you for your explanation! I meant “under me” the place where I would drop it.
Just try it out, with a simple bike as a replacement for the flyer it can be verified.
Note: at least 2 forces act on the coin.
Depends on the wind strength.
Suppose it would be windless, then the coin would move at the speed in the direction of flight with which the plane flew before the throw. However, the coin is quickly braked by the air and then falls relatively straight down.
Of course, it melts in the air due to the flat shape. The exact impact point is therefore difficult to calculate. But it usually lies behind the dropping point in the direction of flight.
Would you like to ignore the gravitation? 😉
It wasn’t the case speed.
Sure. Tell the questioner in your words. I explained it as simple as possible in my words.
If something from a plane falling, then the gravity works. Ultimately, this is a throwing parable.
If you let her fall, she’d fall in the direction of flight.
