Unformatted text preview: Motion in One Dimension Physics 104 444 and TA: Pengyi Zhang February 7, 2008 Sheryl Payne Partner: Ben Wright The work presented in this report is my own, and the data were obtained by my lab partner and myself during the lab period. __________________ Abstract The purpose of this lab was to gain an understanding of motion in one dimension, by observing the motion of a low-friction air cart as it moved down a linear air-cushioned track. The track was at an average angle of =2.24. The initial position of the cart was x=0, and the cart was released and allowed to go: 0.4, 0.6, 0.8, 1.0, and 1.2 meters. A stopwatch was used to measure the time of travel. Each trial was repeated 3 times. From this experiment, it was apparent that the velocity of the cart increased with time. By measuring the position of the cart as a function of time, the following equations were verified: a) V x =at b) x=(1/2)at 2 Upon plotting t2 vs. x, and finding the least-squares linear line, = t2 2xa was used to determine a=0.380.03 m/s 2 . In part two, the same procedure was done, except a photogate was used to measure the time of passage of the cart instead of a stopwatch. x (the length of the flag)=10.00 0.05 cm. time of passage of the cart instead of a stopwatch....
