Think of air as a bunch of sand grains but invisible.
When you stick your hand out a moving vehicle, and prop ur hand in a slightly upward position, think about what happens to your hand?
You catch a lot of sand (air) on the palm side of ur hand to the point where it feels like it’s pushing your hand backwards.
While on the top side of your hand, you basically block all the sand (air).
In the palm of your hand where theres a lot of sand, we call this the high pressure zone.
(Abundance of air molecules that are slow moving as they are stopped)
While on the top side of your hand, where there is no sand, we call this the low pressure zone.
(Lower than normal air molecules creates a vacuum as it tries to find anything to fill the void being created – your are catching what should be there and pushing it to the high pressure zone.)
Because the world likes balance, the low pressure sand looks for a way to fill the void (vacuum) and since the high pressure zone wants to also achieve normal balance, it will push its way (Lift) to the low pressure zone and help fill that void.
It will push ur hand (wing) if it has to causing you to feel your hand pushing back.
