PHY 101 | One Dimensional Motion Lab Report Student Name ________________ Partners ___________________________ Section Number________________ Introduction
Pre-Laboratory Questions 1. What is the speed of a person or object? How does velocity differ from speed? 2. What does the slope of a position-time plot represent? 3. What does it tell you about the direction of the moving person or object if the slope of the position - time graph is positive? 4. What is the acceleration of a person or object that is moving at a constant velocity? Part 1: Distance Matching

1. Would the Motion Detector work better or worse in detecting the motion of your body if you put one arm in front of the detector, instead of your body core? Explain why you think this would be better or worse. 2. What do you think is the average walking speed for a student on the Polytechnic Campus? How could you determine if your prediction is accurate? 3. Estimate how many miles the average Polytechnic student walks each day on campus. Do you walk more or fewer miles than the average?
Part 2: Constant Velocity Data Table: Run Slope (m/s) Mean (m/s) % difference #1 0.218 0.21 3.81% #2 0.266 0.27 1.48% #3 0.405 0.41 1.22% Part 2 Questions: 1. If a graph shows the position and time for a moving object. How does the slope of the line on the position-time graph relate to the velocity of the object? 2. How does the steepness of the line on the position-time graph relate to the speed of a moving object? 3. Sketch and explain: How would the velocity (not position!) vs. time graphs look like if the cart were moving toward the motion detector instead of away?
Part 3: Constant Acceleration Data Table: Item Value Acceleration (slope) 0.872 (m/s 2 ) Acceleration (mean) 0.87(m/s 2 ) % difference 0.230% Part 3 Question: 1. How does the acceleration determined in the plot of velocity compare to the average value of acceleration from the plot of acceleration?
