How is the lift formula in aerodynamics derived?

[ykobe23]

I'm currently doing the IB (equivalent to A levels) and we have to do a research on a subject and i took aerodynamics, specifically lift and can someone explain to me how the lift formula(F= Lift coeffecient x area x air density x velocity squared ) is found ?

Thank you very much

It is found simply through empirical data. The lift coefficient is a proportionality constant that has to be found experimentally, numerically or, rarely, analytically. It isn't a robust physical formula. The more physical formulae for lift and drag are much more complicated.

(F= Lift coeffecient x area x air density x velocity squared ) is found ?

Thank you very much
