That too, but that point was essentially already covered and some just couldn't see it.

Even if you can't "see" it, you can use basic physics to tell what happened from the results.

Think billiards....can you ever hit a stationary ball on the left side and have it go left? No, not possible. The only way that the target ball can go left is if it was moving left before impact with more momentum in that direction than the other ball had in the opposite direction.

You can use these concepts to know who was moving into who without ever seeing the contact. (You have to see it enough to rule out flopping, of course).
