Eli5 what bernoulli’s principles is and how it works for aviation. Been watching videos about it and still cant wrap my head around it, thanks heaps for any help.

the basic idea of bernoulli’s equation is that the amount of energy in a streamline is constant.
if you’ve ever seen a wind-tunnel where they had white smoke snaking across an object, that smoke is caught in a streamline.
energy can be in the form of velocity, pressure, or height. for air, the height difference is trivial, so the air flowing over a wing can be fast *or* high pressure.
how that relates to a wing is complicated. basically, the bottom of a wing pushes air down and the top *pulls* the air above it down. this is a function of geometry and the coanda effect (basically streamlines like to follow objects) but the pulling part on the top decreases the pressure. per bernoulli’s equation, that means the air above the wing moves faster.
