Lift Force

Lift force, abbreviated as L, for an body moving through a fluid (gas or liquid) or air, is the force exerted perpendicular to the direction of travel.

 

Lift Force formulas

\(\large{ L = \frac{1}{2} \; C_l \; \rho \; v^2 \; A }\)

\(\large{ L = \frac{ C_l \; \rho \; v^2 \; A }{ 2 } }\)
