MOTION GRAPHS LAB 2016 Part I: Constant Velocity Materials: Measuring Tape Stopwatches Procedure: 1. Locate a stretch of hallway that is at least 30 meters long and mark it off in 5-meter increments. 2. Choose four people to be Walkers – one slow, one medium, one fast, and one reverse. Choose one person to be Recorder and two timers for each data point. 3. Slow, medium, and fast Walker will start at the 0 m mark while the reverse walker will start from the 25 m mark. When the “go” command is given, they will walk at their designated pace as smoothly as possible, maintaining a constant speed. 4. As the Walker passes each Timer, the Timer will stop their stopwatch. 5. For each interval, the Timers should come up with an average time value for each Walker. These will be recorded on the Class Data Sheet. 6. Return to the classroom and copy the class data onto your lab. Table 1: Data for Walkers of Different Velocities Walkers Distance time (sec) (meters) slow medium fast reverse 0 0 0 0 3.91 5 5.94 4.44 2.77 6.53 10 9.6 7.5 4.6 9.51 15 13.146 11.59 7.47 12.51 20 18.07 15.25 10.08 15.56 25 22.96 19.16 13.07 0 7. In different colors , sketch the graph of each walker’s distance vs. time. Draw a best-fit line for each Walker. Place all data sets on one graph. Be sure to title you graph and label its axes. 8. Directions for making trend lines on Excel instead of hand graphing: a. Copy above data table omitting the very top column of Walkers Distance and time (sec) . Make sure all times are in seconds and no units are in the data table. Paste the table into an Excel file.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
