drag and drop.
good ole integral calculus. Finding all those derivatives and definite integrals was a lot of fun and I never really understood tangent lines to a point on a graph until I was introduced to Calc so many years ago. I can still remember the Derivative of 1/x or -17/x.....The Shuttle was off vertical after the first mile. Air density decays in an almost exponential manner, which is why the most efficient ("synergistic" in missileer's vernacular) trajectory to orbit or suborbit looks a lot like a rectangular hyperbola. It's really a problem of integral calculus.
As for the force of gravity, it's sensitive to altitude. Even at a low exoatmospheric altitude of 250 km we're already at the 9m/s² mark. cn

thanks.
Is it really that simple?
