this is a pretty good detailed explanation: https://fermatslibrary.com/s/how-airplanes-fly-a-physical-de...

the summary being:

- The vertical velocity of the diverted air is proportional to the speed of the wing and the angle of attack.

- The lift is proportional to the amount of air diverted times the vertical velocity of the air

it also debunks the myth of "air flows faster on the top side of the wing, causing lift"
