I'm trying to implement some physics in a game I'm coding and need help with understanding some basic concepts. I have two ships in space of different size and mass. Can somebody please explain to me how to determine what happens when the two ships collide? How do I know if when A collides with B: A might stop completely and move B, or A might move B and keep moving at a slower rate, or A might move B and bounce in the opposite direction? I don't know if this seems like a silly question or not but I would appreciate any help anyone can give. Thanks!
