Title: Gee, Did Class Just End?

Background: School hallways seem wide enough, until the rush starts.

Process: Remember to include axis labels and units in graphs and units in all calculations.

1. Make a simple time-position graph of an exchange student returning to their class from guidance. There

    are 40 minutes left in the class. Think: is the motion continuous? at an even pace?

2. a) What is the point of reference?

    b) the frame of reference?

3. Sketch another time-position graph of the student leaving the class with their classmates after it has

    finished. Think: is the motion continuous? at an even pace?

4. If it takes 1.8 mins for a student on crutches to travel 58 m down an empty hallway, what is their

    average velocity?

5. At 10:01 a teacher intern is 8.5 m from their class and at 10:03 they are 61.2 m from it. Find their

    average velocity for this time period.

6. Plot the following data in a time-position graph of a student walking to their locker.

    time (min): 0.5 1.1 2.4 3.6 4.2 5.3 6.4

    position (m): 2.1 4.1 23 14.2 16.5 21.4 25.7

7. Now, find the slope of the graph.

8. What does the slope tell us about motion of the student?

9. Suggest ways the effects of hallway congestion might be minimized.

10. How would you gather data to analyze the success of your suggestions? Think: before and after.
