A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- Avoid politics (NEW RULE as of 5 Nov 2024, trying it out)
- Posts must be original/unique

Not really crazy, just high school physics
https://en.wikipedia.org/wiki/Bernoulli%27s_principle
racecars use it but in the opposite direction, which is why the faster they go the more they stick to the ground

Bernoulli's principle is certainly involved, but the full explanation is more complicated and arguably beyond high school level:

See #3. Wings are not constrictions in a tube.
From your source:
Sure, it might be more complicated and there are other forces at play. Also, top and bottom air molecules may not reach the backside of an airfoil at the exact same time, but that doesn't diminish the effects of this pressure differential on lifting force.
Sorry, i meant in the classical form of bernoulli's equation it's been a while. It's common for people to suggest the wing is half a venturi, then try to apply 1DOF algebraic equations which don't work here.
