What's the equation for the force of a lift. Drag formula is 1/2 ρ∆v^2 C A. And if you need the constant how would i determine the lift constant for a semi circle shape which spins sideways and has an acceleration of approximately 8.5 m/s down (should be gravity which is 9.8 ms/s). It is moving forward at an initial speed of 62.9 m/s if that helps.(adsbygoogle = window.adsbygoogle || []).push({});
