The initial and final momentum, as well as percent error, were calculated using Microsoft Excel.

Analysis In this experiment, the distance between leading edges of the flag (change in x) was measured with a ruler, the masses were found using a digital scale, and initial velocity was measured Capstone software configured with the Pasco data acquisition system. Percent difference was then used in order to compare all of the values to one another. Once again the initial and final velocities were found in order to calculate the initial and final momentums. For the elastic collision with both masses moving, the two gliders were put at different ends of the air track and were then pushed towards the center, allowed to hit one another and bounce off. The same process is done for the elastic collision, but bumpers were attached to the front of the gliders instead of the inelastic collision pin. The initial and final velocities were found through the two photogates for each glider and were then multiplied to the mass and added together to get the initial and final momentums. The second glider was placed between the two photogates, the first glider was then pushed down the track to hit and stick to the second glider. The inelastic collision with one mass at rest was done using the inelastic collision pin and putty receptacle attached to the front of each glider. For each type of collision (inelastic collision with one mass at rest, elastic collision with one mass at rest, and elastic with both masses moving), three different masses were measured. Procedure The materials used for this lab are the apparatus shown in Figure 1 that consists of: a Pasco two meter air track, gliders with flags, glider weights, inelastic collision pin and putty receptacle, bumpers, air blowers, two photogates, Pasco 850 Universal Interface, computer, and Pasco Capstone software. These calculations were then used to prove that the total initial momentum is equal to the total final momentum. Percent difference was then calculated (initial momentum final momentum) divided the initial momentum multiplied 100 to get a percent. The equation for total final momentum for this experiment was (where is the first mass times its final velocity, and is the second mass times its final velocity). The total initial momentum is calculated (where is the first mass times its initial velocity, and is the second mass times its initial velocity). In this experiment we calculated the total initial momentum, the total final momentum, and the percent difference. Momentum is calculated multiplying the mass of an object times the velocity of the same object.
