Experiment 6: Investigating motion using video processing software Part One Method: We switched on the laptop and connected the web cam into the USB. Once this was done we made sure that the web cam was working correctly and as soon as this watched checked we began to set up the practical part of the experiment. We then pressed record on the web cam using the software VISILOG and recorded the ball being thrown in the air next to a vertical ruler (one metre). Once this had been done we stopped the recording and the replayed the video and once we were happy, using the software, we recorded the position of the ball frame by frame. Below are the results for the first part of the experiment: Results: Time (s) Height (m) Speed (m/s) Acceleration (m/s2) 0.00 0.057 0.00 0.00 0.03 0.133 2.53 84.44 0.07 0.260 3.18 16.04 0.10 0.380 4.00 27.50 0.14 0.510 3.25 -18.75 0.17 0.615 3.50 8.33 0.20 0.702 2.90 -20.00 0.24 0.793 2.28 -15.63 0.27 0.865 2.40 4.17 0.30 0.927 2.07 -11.11 0.34 0.970 1.08 -24.79 0.37 1.006 1.20 4.17 0.40 1.032 0.87 -11.11 0.44 1.050 0.45 -10.42 0.47 1.057 0.00 -15.00 0.50 1.050 0.23 7.78 0.54 1.025 0.62 9.79 0.57 0.999 0.87 8.06 0.60 0.963 1.20 11.11 0.64 0.909 1.35 3.75 0.67 0.840 2.30 31.67 0.71 0.767 1.83 -11.87 0.74 0.688 2.63 26.94 0.77 0.586 3.40 25.56 0.81 0.477 2.73 -16.88 0.84 0.365 3.73 33.61 0.87 0.235 4.33 20.00 0.91 0.079 3.90 -10.83 We can then draw a graph using the results and the first graph I have drawn (graph one) is of height of squash ball against...
