Question by LSPressWorks · Jul 24, 2017 at 10:00 PM · physicsballtrajectorycannon

Trajectory of a Ball

Hello,

I have searched about for this answer with no luck. I am currently looking to resources at large for an answer but have encountered two different images. using a ball scaled to 1,1,1 with a mass of 10 and force applied form 180-1,000 I was anticipating an arc with identical left and right sides. By numbers this would express it's height from the point of origin. (1,2,3,4,5,4,3,2,1), and what I am getting is (1,2,3,4,5,2,0).

Visually: I am anticipating this

and getting this...Only it seems exaggerated.

reducing the drag to .225 corrects the anticipated flight path to a perfectly flat arc, which seems "off" as well at this point.

I think I fiddled too much and am not sure anymore. Which one is correct?

btw, here is a video of the paths. The first shot is .225 drag, the second - last are 1.0 drag at variable force. https://youtu.be/_hC5diD6-Ak

Code would be usefull to understand what you are doing?

Could be due to the fact parabloic curves with gravity aren't the same all the way due to gravity taking effect.

Were you following any tutorials on this or not?
