Homework Help: conservation of momentum

Posted by Melanie on Sunday, November 30, 2008 at 11:17pm.

If you have two pucks elastically collide on an air table, and then analyze the momentum vector diagram of the situation, you encounter an increase in momentum. What are possible reasons as to why there was a gain of momentum.

Note: Both pucks were pushed from the end of the table, and collided approximately in the middle.

I believe, depending on the force you exert on the two pucks, the puck with the greater force has caused the system to gain momentum.

If you have any other suggestions, or if you think my answer is incorrect please help and explain. I am a bit confused.
