AP Momentum Lab

I would like to tie in the momentum lab with enrgy conservation during collisions. I had asked you find out how much KE was lost during the collisions. This takes writing about five equations and copying them for each run. I would like you to identify which runs had the greatest losses and see if you can explain why. Do this with a paragraph or two citing percent differences and characteristics e.g. both carts moving , lots of bars, or whatever is appropriate. Bring it in tomorrow.
