Wendy Candler 2/4/08 Lab 1 Write-up Graph Matching Purpose In this lab we discovered how to read and interpret graphs of distance vs. time and velocity vs. time. These basic graphs allow the experimenter to easily tell the direction an object is going, its speed, how far it travels, and whether it is accelerating or decelerating. We used a motion detector hooked up to a graphing program on the computer to track and record the motion of a student walking across the room. The sensor used a high frequency sound pulse and the speed of sound to determine the distance to the student or object. It is important to be able to install, understand and operate the sensors and computer programs used in these experiments. Technology and graphical representations are essential to testing theories, and recording findings. Graphs are used by scientists in almost all types of experiments as an easy way to visually observe and analyze data collected. It is important to be able to read and understand the information presented at a glance, and to be able to use it to make future predictions. Analysis Questions Distance vs. Time 1. Part B: When matching this graph, we started at the 1 meter mark and after 1 second moved to 2.5 meters in the span of 2 seconds. Then at the 6 second mark we moved to 1.75 meters
