Emile Zimmerman PHYS 1110L Introduction In this assignment, we will be investigating the effects of velocity and acceleration on the position of the moving man. I believe we will see an increase in position with the increase of both velocity and acceleration. I believe that velocity will have a constant result whereas acceleration will have an increasing result. 1. Use the playback feature to answer the following questions. a. What happened to the blue position slider as the man moved across the screen? The blue slider slid from left to right as the man moved across the screen. b. What happened to the red velocity slider as the man moved across the screen? The red velocity slider stayed in place as the man moved across the screen. 2. Use the playback feature to record the man's position and velocity data. Time (s) Position (m) Velocity (m/s) 0.0 -7.95 1.2 1.0 -6.75 1.2 2.0 -5.65 1.2 3.0 -4.45 1.2 4.0 -3.15 1.2 5.0 -1.95 1.2 6.0 -0.75 1.2 7.0 0.4 1.2
8.0 1.65 1.2 9.0 2.75 1.2 10.0 4.05 1.2 3. Plot your data in the graphs below:
4. According to your graphs... a. What shape is your position graph? The shape of the position graph is an upward diagonal. b. What is the slope of your position graph? The slope of the position graph is 1.2 c. Why does or doesn't your answer to b. make sense? This answer makes sense to me as the velocity is 1.2. d. What shape is your velocity graph? Is it horizontal, vertical, or diagonal? The shape of the velocity graph is horizontal. e. Why does or doesn't your answer to d. make sense? This makes sense as the velocity stayed constant throughout the experiment. Constant Acceleration 1. Reset all of the man's values to zero. 2. Using the position slider, set the man to stand near the tree. Give him a velocity of 0 m/s and an acceleration of 0.5 m/s 2 . 3. Click 4 to start the man in motion until he hits the wall, then hit ; to stop recording. 4. Use the playback feature to answer these questions. a. What happened to the blue position slider as the man moved across the screen? The blue slider rapidly increased from left to right as the man moved across the screen. b. What happened to the red velocity slider as the man moved across the screen? The red slider moved up at a constant rate as the man moved across the screen. 5. Use the playback feature to record the man's position and velocity data. Time (s) Position (m) Velocity (m/s) 0.0 -10 0 1.0 -9.77 .48 2.0 -9 1 3.0 -7.75 1.5 4.0 -6 2

5.0 -3.75 2.5 6.0 -1 3 7.0 2.25 3.5 8.0 6 4 9.0 10 0 10.0 6. Plot your data in the graphs below: 7. According to your graphs... a. What shape is your position graph?
The shape of the position graph is an upward curved live. b. Why does or doesn't your answer to a. make sense? The answer does make sense because the velocity is increasing with time which would create a curved shape. c. What shape is your velocity graph? The shape of the velocity graph is an upward diagonal line, which takes as sharp turn downward when the man hit the wall. d. Why does or doesn't your answer to c. make sense? This make sense because the man was accelerating while moving across the screen, then when he hit the wall he stopped moving. e. What is the slope of your velocity graph? The slope of my graph is .5s^2 f. What does the slope of the velocity graph represent? The slope represents the acceleration of the moving man. In conclusion, the lab confirmed my initial hypothesis that position will increase in both acceleration and velocity. With velocity, we saw a straight diagonal line in relation to position whereas with acceleration there is a curved diagonal line. The straight line shows that the amount gained over time was constant and the curved diagonal line showed an increase gained over time. The velocity charts for the experiment reiterate that by showing a constant horizontal line for the first experiment and a constant increasing diagonal line for the second experiment.
