### In Topic: How to find the net normal force acting on all object?

08 January 2013 - 05:57 PM

I read about impulses, but the only thing I don't understand about them is when to apply them (right at the collision, or at the beginning of the loop? if it is in the beginning of the loop I would have to store them at collision?). Also, what should I apply them to, the current velocity or a temporary velocity that I will later apply to the current velocity? Also, currently I implemented a discrete system, and there is a lot of jittering (especially when objects are supposed to be at rest), is there any way around that?

Thank you

Thanks for the replies, I did it the quadratic way and it worked, but I might try the other ways later.

Thank you for the reply, but I don't quite understand what you mean by using coordinates where one of the circle is not moving? Like find relative velocity or relative position? And for finding the shortest distance between a segment and a point, what would be the segment and what would be the point?

I think you should take a look at this: http://www.mediafire.com/?3d6tk67ppq3h4lb

Thank you!
