Pygose: To calculate a w average speed of a person who is walking at uniform speed. Materials: - m measuring tape Procedure: 1. Using the tape measure and masking tape, mark OH a lmeter track at every 10 meters 2. Have a student with a stopwatch and some paper sit at every lClmeter interval. 3. Now walk the track at a normal pace. You should start a few meters hack to g to the normal speed. Once you reach the starting line, all 4 timers should E signaled to start. As you reach each lU-meter interval, that timer should record the corresponding time. 4. Once you reach the nish line, should TL-Vlk hack to the start: picking up your times at each interval. Observations: PartA IGraph one of the trials onto a distance time graph and nd the slope of the line. Questions 1) Based on your graph, a) What do you notice about your motion? 1)) Did you walk at constant speed?I Hovu.r do you loiow'.' c) How does your instantaneous speed compare to your average speed?I 2) If you had tripped along the track, how would that have affected your results? 3) Suppose that we were on an incline, howl.r would that have a'ected your results?
