Three collisions are elastic and three are inelastic. Determine which collision type took place for each collision. Support your conclusion with the data and observations from the lab. Elastic Collisions: “The velocities of both objects after the collision are most likely going to be different than what they were before the collision.” Collision one, two, and five are elastic collisions. Collision one, mass one has an initial velocity of five and a final velocity of negative five, mass two has ana initial velocity of negative five and a final velocity of five. Collision two, mass one has an initial velocity of five and a final velocity of negative eight-point-thirty-three, mass two has an initial velocity of negative five and a final velocity of one-point-sixty-seven. Collision five, mass one has an initial velocity of five and a final velocity of zero, mass two has an initial velocity of zero and a final velocity of five. Inelastic Collisions: “The objects share the same final velocity in this case.” Collision three, four, and six are inelastic collisions. Collision three, mass one and mass two have a final velocity of zero. Collision four, mass one and mass two have a final velocity of negative one-point-sixty-seven. Collision six, mass one and mass two have a final velocity of one-point-sixty-seven. 2. Using your data, how are you able to determine if conservation of momentum occurs in each collision? Using my data and Newton’s Second law of motion you can determine if conservation of momentum occurs in each collision. 3. Write a conclusion for this lab. Also, make sure to discuss the conservation of momentum and how it applies to collisions. Each collision is different in mass, velocity, and momentum so the outcomes for each differ tremendously. In the six collisions, three are elastic and three are inelastic. Collision one, two, and five are elastic collisions meaning both masses are going to differ from what they were before the collision happened. Collision three, four, and six are inelastic collisions meaning in this case the masses will share the same final velocities. The conservation of momentum applies to collisions as per Newton’s Second law of motion. The rate of change momentum of a system is proportional to an unbalanced external force acting on it.
