Honestly I want to know how do they fly
In: Physics
Airplanes use a quirk in the physics of moving air. Take a sheet of paper and hold it lengthwise and horizontal by pinching the far 2 corners. You should have a sheet of paper that the end closest to you hangs down. As you expect it would. Now turn your hand ever so slightly so the handing edge of the paper forms a rainbow shape. No blow gently OVER the top of that curve.
You will see the paper lift up towards the top of curve. That is called “lift” planes use the same principal except they use big jets or propellers to make the air move super fast and use the long curve of the wings to make a lot of lift. Enough lift that it can lift multiple tons of metal and cargo.
Every object/person in the planet is surrounded by invisible forces being applied from every direction.
When you stand still, you do because you have a force pushing you forward and another of the same intensity pushing you backwards.
When a plane goes forward, the angle of the wings, it’s shape and the speed of the aircraft makes the air right above the wing be less concentrated (not a vacuum, but you can think of that that way if it helps).
With less air present at the top of the wing, the forces that pushes the wing down becomes weaker than the forces pushing the airplane upwards.
That’s the principle.
The typical principle is that thrust from the engines moves the plane forward, and forces air over a specially shaped surface on the wings. This means that as the wing moves through the air it produces lift. This overcomes the opposing forces of drag (air resistance) and gravity. Thus a plane can fly.
