Exactly.. if they didn't stick together then they didn't collide, because they were pulled apart by other collisions at the instant in question. And this can happen even if they had negative relative velocity before the contact, as in my second example image. The two small pieces are in contact...

For anyone who is interested, I've been researching this problem for the last few days and discovered that it's more complicated than a single calculation. It's a system of equations, but some of them are inequalities, e.g. the non-penetration constraints, and may or may not bound the solution...

Ok, but doesn't that treat all the objects as if they are glued together? The yellow objects can't pull each other. It doesn't make a difference in this case, but in other cases there might be separations. That's really my problem: figuring out which objects have the same velocities after the...

I'm trying to figure out how to calculate collision response in a simulation I'm working on. Here are the details: 2D Objects are made of axis-aligned edges and do not rotate Object masses are whole numbers Collisions are completely inelastic No friction Collision/separation times are...
