Huynh, Anne July 14, 2008 Partners: Vinh Dang, Ben Lee, Tania Gomez Conservation of Linear Momentum Purpose: The purpose of this experiment is to demonstrate the conservation of linear momentum for perfectly inelastic collisions. We used equations for initial momentum and final momentum to show that the percent difference between the values are small, specifically under 10%, to show that linear momentum was conserved. Summary: Case 1 2 3 4 Avg. % Diff. 4.16 3.58 4.09 5.22 4.262 Here we have a summary of the percent differences in each case, whether they had no added mass on either glider, mass on one glider, or mass on both gliders. The masses in each case were determined as well as the time it took for the system to pass through each photogate. From there the velocity was calculated. Each velocity was plugged into the corresponding equations for

Unformatted text preview: momentum. The average percent difference between initial momentum and final momentum came to be 4.262%, demonstrating that linear momentum was conserved. Experimental Error: Some errors may have occurred with the glider, such as imbalance in the setup or inaccurate weighing on the electronic balance. Another factor is our measurements because the ruler can only be read to a certain degree of accuracy. The percent difference is not perfectly zero because there are other external forces besides gravity in this experiment such as friction. Giving a slight push with too much force would affect time the glider took to pass through the photogate. As listed above, our average percent difference between initial momentum and final momentum is 4.262%....
