William asks…20 years since physics...What is the formula to calculate terminal velocity?Google it my A ss. Read the question. It has been over 20 years since I was in college. I'm lucky to be on the internet at all.Nancy answers:In a vacuum, v = at^2 (velocity = acceleration times time squared)
The acceleration above the earth is roughly 32 ft/sec^2, or 9.8 meters/sec^2
In the atmosphere, the terminal velocity is going to be affected by the density of the air and the shape of the falling
