There are two types of collisions; elastic, and inelastic. Each of these collisions takes place every day in our world. They can be evidenced by just about everything. From two cars colliding on the highway, to a tennis ball is hit by a racket, and even a cue ball hitting in the 8 ball, collisions are all around us. For this lab, we focused on inelastic collisions, a collision in which the kinetic energy of the objects is not conserved. Inelastic collisions also obey the Law of Conservation of Momentum, which states that the total momentum of a closed system of objects, without any interactions from external agents, is constant. Although our experiment was not a perfectly inelastic collision, it was close enough to fulfill the purpose of the experiment; to show that the momentum is conserved in the collision of our two carts, as well as show that the kinetic energy

Unformatted text preview: of the system was not conserved. Our hypothesis is that if momentum is conserved during a collision, regardless of mass, the percent difference of momentum before and after the inelastic collision will be zero. This is supported by the Law of Conservation of Momentum. The law states that total momentum, p=mv, of an isolated system is constant. Interactions within the system do not change the system’s total momentum. Also, during the inelastic collision, we predict that energy will not be conserved. This is because kinetic energy is defined as ½ multiplied by the mass of an object multiplied by its velocity squared (K=1/2mv^2). In order to make our experiment inelastic, our carts had Velcro on the ends where the collision took place....
