Momentum, Energy, and Collisions (MBL) Pre-lab Assignment

Your name: _____________________

Print this page, record your answers on it, and show it to your lab TF at the start of your lab session. In the experiment you will analyze several 1-D collisions to see whether momentum and/or kinetic energy are conserved. We'll analyze three simulated collisions here using the same methods.

CollisionInitial momentum of blue cart Initial momentum of red cart Final momentum of blue cart Final momentum of red cart Total initial momentum Total final momentum Ratio of total final/total initial
1 0 ______ ______ ______ ______ ______ ______
2 0 ______ ______ ______ ______ ______ ______
3 0 ______ ______ ______ ______ ______ ______

Is momentum conserved in these collisions? Justify your answer.




CollisionInitial K of blue cart Initial K of red cart Final K of blue cart Final K of red cart Total initial K Total final K Ratio of total final/total initial
1 0 ______ ______ ______ ______ ______ ______
2 0 ______ ______ ______ ______ ______ ______
3 0 ______ ______ ______ ______ ______ ______

Is kinetic energy conserved in these collisions? Justify your answer.




Classify each of these collisions according to the definitions given in the lab write-up.
Collision 1:Super-elastic Elastic Inelastic Completely inelastic
Collision 2: Super-elastic Elastic Inelastic Completely inelastic
Collision 3: Super-elastic Elastic Inelastic Completely inelastic
