hello, i've been asking allot of questions lately, but i have learnt allot thanks to all the help from these forums, and helpful people.. now to my question.. i have two spheres, one of which is a cue ball. Both balls have the same radius.. if I am shooting the ball very close to the target ball, at a slow velocity it passes by. But the same shot at a higher velocity on same trajectory let's say at 20 m/s hits the target object.. I have no idea why this is happening. Does anybody have any ideas of what might cause this?
