I just saw this: http://1.bp.blogspot.com/-uG3_RgX9JA0/TboU21S9gNI/AAAAAAAAD5w/zkR3VV91S8Y/s1600/6733226c0117931aa6df7c8d3a8e7127.jpg While it's a commendable effort, the physics is brutally wrong in it. Would it be pretentious to try to correct it?

@edman lol It's like every highschool student thats taken a physics class thinks they are some ace Physicist. I like his little Acceleration vector that assumes acceration is constant in the x and y direction lol

@edman If i use his assumption of 5m radius AND his assumption that magnitude of her velocity does not it is literally a two step process. Giving 2357g. But in my opinion the radius is much larger. BUT A MORE IMPORTANT PHYSICS QUESTION is how can pegasi even fly? I mean there wings are far to small and the body mass is too high!

@starlightbolt I don't know if it's a two-step process. I would use a = v^2/r for the centripetal acceleration. To calculate the overall acceleration at any point is somewhat involved, because the portion of gravity that contributes to the centripetal acceleration is varying as a function of theta (or as a function of time, if you prefer). However, it's not too difficult to calculate the maximum g-forces experienced (at the bottom of the arc). As it turns out, I'm actually making an infographic about this right now.

@edman Actually, I should correct myself: If you only want the acceleration in g forces, then it's actually quite trivial, since you would ignore the acceleration due to gravity.

@edman yes thats what i used. Its a two step process because once you get the centripetal acceleration you just find the point where the acceleration experianced is the greatest (bottom as you said). It will only vary from 0(top) to +1g(bottom) so you just add 1g to the centripetal to balance out the acceration
