Amber Patel Collisions Purpose: To use law of conservation of energy to find the ratio of mass of two colliding objects. Procedure: To do this we are going to watch three videos of collisions of cars on air tracks. The air track has almost zero friction so friction can be neglected in our experiment. After watching the videos we used java applets to get the points of the cars with respect to time in each collision. The graphical data is then used to measure the initial and the final velocity. After finding the velocities we are going to find the ratio m1/m2 by using law of conservation of momentum. Observation: Experiment 1: The graph when two cars collide and both move in the same direction

In experiment 1 it was seen that both objects went in the same direction thus their m1/m2 ratio was very small close to a 0.009. While in the case when one object comes to rest and other moves the ratio was small but not too small; it was 0.5. But in case of moving in opposite direction the ratio was greater than 1 and large; it was 5.3. This experiment shows us that the ratio of mass can help judge the movement of the two bodies after collision....
