Unit I Assignment: Conceptual Experiment Worksheet
Running and Walking Problem
A research team developed a robot named Ellie. Ellie ran 1,000 meters for 200 seconds from the research building, rested for 100 seconds, and walked back to the research building for 1000 seconds. To find out Ellie’s average velocity for each case while running, resting, and walking, begin by plotting a graph between position and time.
Complete the Graph: The graph below will show you Ellie’s distance from the research 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.

Questions: Answer the questions below using complete sentences and add space as needed.
- Distinguish between speed and velocity.
- List the velocity from greatest to least among running, resting, and walking.
- List the speed from greatest to least among running, resting, and walking.
- If the slope in the plot of distance and time is steeper, do you think the speed of the motion is increasing or decreasing? Why do you think so?Your response should be at least 75 words in length.
- If the slope in the position versus time graph is a curved line, what can you tell about the motion?
Your response should be at least 75 words in length.
