 * Brief Description of Experiment**: We used recorded videos on Logger Pro to find the velocity of each cart using points on a graph. From that information, we used the initial velocity and final velocity to find the intial and final momentum of the cars to show that they conserved momentum from the start of the scene to the end of the collison.

250g (.6637 m/s) + 250g (-.5467 m/s) / 100 = .2925 kg*m/s
 * Sample Calculations:**

All but one of our experiments conserved motion when we calculated momentum. The one that didn't conserve motion was difficult to measure and therefore had human error. On paper provided. Our research was valid because the momentum was very closely conserved. It's very difficult to design an experiment that shows complete conservation of momentum, but we got it within .1 kg*m/s of each other usually. In order to make this experiment better, we would suggest that Logger Pro would have a "zoom" function, so that you can tell exactly where the front of the car is to make it very accurate. //Don't forget to link to your lab report from the lab reports page and to include a link to your lab report in your reflection.//
