Unformatted text preview: Pedro Viteri pjv267 3/3/08 Physics 103M: Laboratory 4 1. Introduction The main objective of the laboratory 4 of the physics course 103m, was to show the relations in kinetic energy and momentum in different types of collisions. The theory tell us that for totally elastic collisions the momentum and the kinetic energy are conserved in the collision and that for an inelastic collision, the momentum is conserved but the kinetic energy isnt conserved. The only condition for the previous laws is that the system as a whole is isolated. This little detail plays a huge role in our experiment, because on earth there are very few isolated systems, although we can eliminate some of the most influential forces. Like friction was largely reduced by using an air track. The other great detail is gravity, if the track is exactly perpendicular to the surface of the earth, gravity doesnt influence our experiment, but even a fraction of a degree of inclination could have created a contrary acceleration and changed the speed. Kinetic energy = K= mV^2 Momentum = P = mV As we can see both quantities depend on the mass and the velocity or speed. As we can see both quantities depend on the mass and the velocity or speed....
