>I said one way was forced to travel more distance in the same amount of time.If something is forced to travel more distance in the same amount of time as the other thing, it obviously is going to require more speed. OR it's a displacement and doesn't actually have to do with speed at all and the speed is just there for velocity's sake as well as to jump start that displacement of air.
Given that a plane can literally take off on a conveyor belt and can glide a significant distance with no input this is the case. In the hot air balloon example I gave, what is it that's even traveling that's causing the balloon to float? Yes the air is hotter and in motion but there is "less air" in the balloon then the dense air outside. This results in the same type of "lift", you would see in an oil drop in water. The same type of pressure difference is occurring on the top and bottom of the wing resulting in lift. The "speed" is just there so the plane can travel faster through the medium of air, as it travels through this medium it displaces it at the same time causing lift.
So lets for back to what was originally said
>Wrong. There's no reason the air on top and bottom have to flow across in the same time.Which is correct because nothing is actually "flowing" to begin with. The air was already there and the plane is just passing through it. Like a ship in water, you're displacing the air moving it from where it is to where it is not. I was referring to the displacement of the air, not the traveling flow of air over it.
Both sides of the wing pass through the air in the same amount of time.
One side displaces more area of air than the other.
So logically the air on the top is literally forced to travel more distance in the same amount of time.
