Physics Labs with Computers, Vol. 1Student WorkbookTutorial Activities: Motion Sensor 012-07000A3. Calibrate the software.• First, make sure that the sensor is one meter from the target.• Second, click the ‘Calibrate’ button in the Motion Sensor window. Result: The softwarecalculates the speed of sound based on the calibration distance (one meter) and the roundtrip time of the pulse and echo4. Click ‘OK’ to return to the Experiment Setup window.Set up a display• In DataStudio, double-click the ‘Graph’ icon from the Displays list. Result: The Graphdisplay shows position versus time.• In ScienceWorkshop, click-and-drag the ‘Graph’ display icon to the sensor’s icon in theExperiment Setup window. Select ‘Position, x (m)’ from the list of and click ‘Display’.Result: The Graph display shows position versus time.Start recording data• In DataStudio, click the ‘Start’ button ( ). In ScienceWorkshop, click the ‘REC’button ( ).• Move a target (such as a book) back-and-forth in front of the sensor. Watch the results onthe Graph display.Stop recording data• Click ‘Stop’ to end data recording.A - 32©1999 PASCO scientific
