Learn to use the slope of a position-time graph to find the velocity. SmartGraphs software can lead you through the calculation of “rise” over “run.” How Fast Am I Moving is the third of five SmartGraphs activities designed for a typical physical science unit of study on the motion of objects. (The other four are: Maria’s Run; Motion Toward and Away; Describing Velocity; and, Was Galileo Right?)
Portions of this activity require a Vernier Go!Motion sensor, an inexpensive device that plugs into your USB port. To use the sensor computers must have Java installed. Otherwise, the activity runs entirely in a Web browser. Preferred browsers are: Google Chrome (versions 5 and above), Safari (versions 4 and above), Firefox (version 3.6.10 and above), and Internet Explorer (version 7, 8, or higher; note that version 6 or below does not work).
