Well "Jim's make it up as you go along Physics manual" says that there is
greater pressure against the air molecules in front of the moving ball. ... etc.
Strike 1.
Hint: If the curve ball is spinning about a vertical axis, what does this say about the flow of air on the left and right sides of the ball?
Here's the windup ... and the pitch ...
Ok, then how do you explain a frisbee that can curve either way, even though it's always thrown with the same direction of spin. And please include the coriolis effect in your explanation (now that it is implimented in JSBSim.)
Thank you. :-)
