The main purpose of the experiment was to investigate two ideas: 1) if momentum is conserved, and if so, if it was conserved in both elastic and inelastic collision; 2)if kinetic energy is conserved, and if so, if it was conserved in both elastic and inelastic collisions. After a trial of fifteen collisions between two carts, having changed either the initial velocity of each cart or the mass of each cat in each trial, the total momentum before and after the collision was calculated as well as the total kinetic energy before and after the collision, by using the data gathered from the trials. Then, two graphs were formed using the data. One of total final momentum VS total initial momentum and the other of total final kinetic energy VS total initial kinetic energy. After drawing a line of best fit for each graph, the slope of each graph was then calculated. The slope of the momentum graph was very close to zero, which means that momentum is conserved in both elastic and inelastic collisions. The slope of the kinetic energy graph was 0.5297, and proves that kinetic energy is only conserved in elastic collisions and not in inelastic collisions.
