ker emitted a spark .2 seconds we circled every fifth dot and measured the distance between our zero and the circled dots. To find displacement we measured one dot around each circled dot and subtracted the two numbers. Next we took the displacement and divided it by .2s to find the velocity. We did this for every half a second to 4.5s. We proceeded to fill in the chart with the information we discovered. After completing the chart we plotted points on two graphs, one of distance and time and the other of velocity and time. Next we forced straight lines on the graphs and found the slopes. On the velocity-time graph we also discovered area under the curve, which gave us distance. We compared this to the distance we had measured and found percent error. Using the graphs I found that distance is in a direct relationship with time when there is constant velocity. There is no acceleration when there is constant velocity and that there is not a direst relationship between time and constant velocity....
