Conceptual Experiment
Purpose: To visualize the relationship between displacement, velocity, and time through graphical analysis.
A fundamental job of physics is to describe the motion of an object. In order to do this, you need basic elements such as displacement, velocity, and time to depict it. In this activity, you will investigate how constant-paced linear motion is depicted and how you can calculate the velocity. First, practice using the worksheet with the sample problem below. Use the Unit I Project Worksheet for this unit.
For the sample problem, let’s use a simple case. Let’s assume that you are walking from your house at a constant pace for 100 seconds to get to the 100 meter-mark, and you come back to your house at the same pace.
Please click on the following link for a video with detailed instructions on how to plot the relationship between time and distance and how to obtain the velocity.

Unit I Assignment: Conceptual Experiment Worksheet
A college student named Nova walked 500 meters for 500 seconds from her dormitory building to find her favorite bench in a park. She called her mom and talked for 100 seconds at the bench, but suddenly she remembered that she did not turn off the gas stove. So, she returned her dorm by running for 100 seconds. To find out Nova’s average velocity for each case while walking, resting, and running, begin by plotting a graph between position and time. Please be aware that the walking mode is a positive direction and the running mode is a negative direction of Nova’s motion.
Complete the Graph: The graph below will show you Nova’s distance from her dormitory building at a given time. Click the right cursor in the graphic area, and click on “Edit Data,” then select “Edit Data” or “Edit Data in Excel.” The time column is given to you. Enter the data in the distance column by reading the description shown above. The outcome will be shown in the graph. (20 points)
