T. 1.1.1.3.4.1.5
Activity A:
Get the Gizmo ready:
• Click the red Reset button on the stopwatch.
• Be sure the Number of points is 2.
Runner position
In the Gizmo, run the "race" many times with a variety of different graphs. (The red points on the graph can be
dragged vertically.) Pay attention to what the graph tells you about the runner.
1. If a distance-time graph contains the point (4, 15), what does that tell you about the runner? (Be specific,
and answer in a complete sentence.)
2. Look at the graph to the right. Notice where the green probe is. If you could see 1
the runner and the stopwatch at this moment, what would you see?
