These basic graphs allowed us to easily tell the direction the subject was going, its velocity, its range of motion, and whether it’s accelerating or decelerating. The purpose of this lab we discovered how to read and interpret graphs of distance vs. 5 m away from the detector within 1 second, held position for 2.5 seconds, and then walked away from the motion detector stopping at 3 m within 3.5 seconds. After maintaining position for 1 second the subject walked closer to the detector for 1 m with higher velocity, stopped. For file C, subject immediately walked towards the motion detector for 1.5 m with a constant velocity and stopped at 1.5 m within 4 seconds. After maintaining position for 4 seconds the subject walked towards the motion detector for about 1 m, stopped at about 1.7 m away from the motion detector within 2 seconds, and maintained position about 4 seconds. For file B, a graph had to be formed from the subject’s motion and position with the subject standing about 1 m away from the motion detector for 1 second, after 1 second the subject walked about 1.5 m from the detector with constant velocity and stopped at 2.5 m away from the motion detector within 3 seconds. time graph would look like if the subject walked faster and was verified with the motion detector afterwards. For file A, the prediction was made of how the position vs. time graph would look like if the subject walked faster then was verified with the motion detector afterwards. A prediction was made about how the position vs. time graph was formed from the subject’s motion when the subject was standing about 1 m from the Motion Detector and proceeded to walk away from the detector with constant velocity. Using Logger Pro “Graph Matching,” files a, b, c, d, and e each file was opened and the first position vs. Then predicting, sketching, and testing the position versus the timed kinematic graphs. For this Graph Matching lab, our goal was to examine the motion of a student walking across the room. At from these graphs, it can be seen that the slant of the diagram told how the subject is moving positive or negative while the steepness of the slope shows the velocity. These graphs sloped at various positions relying on how and when we moved. My lab partner and I walked towards and far from the Motion Detector to create a few different positions on a graph.
