Motion Matching Experiment
Position vs. Time Graph
Start-up Procedure:
Open Homedirs / Honors Physics / A Motion Mapping General Physics. Drag entire folder labeleld
Motion Matching Data Studio Files to desktop.
Open Motion Matching Folder . Open the first file - Motion Match-sw1
Data Studio will open. Answer questions:
* Chose an options set? Yes.
* Select Setting file: Common Feature Set.
* Answer Yes when asked if Data Studio should add a motion sensor to the activity.
* Click the Done box on the XplorerGLXFile Manager box opens.
Check Motion Sensor . Long range setting; sitting flat on table, near the edge; sensor face is perpendicular to ground.
Data Collection
When everything is ready, hit start to start recording data. There is a 3 second delay before data collection begins.
Between runs of same graph : Use the “Experiment” dropdown to “Delete Last Run Data”.
Between graphs : Do NOT open another copy of Data Studio. Either close the one you are using and open the next file from the HP Motion Matching folder or open the file from within Data Studio using the
“File / Open” drop down. The laptop will freeze if more than one copy of Data Studio is open!
Analyzing the Data : complete these in a Word.doc and save. When done, you will be placing your responses in a Drop Box on Homedirs

5.
What physical quantity does the y-intercept on the position vs. time graphs 1 through 3 represent?
6.
What physical quantity does the slope of the position vs. time graphs 1 through 3 represent?
7.

Click any of the 90+ graphs of Motion Match-sw1 .
10. Give a qualitative, objective description of your motion during the time intervals given below.
Record descriptions in the Word file in a table titled “Graph Matching Observations & Results Table.”
11. Using the slope tool, determine three slope values over the specified intervals - one value at the beginning of the interval, one value ½ way into the interval, and one at the end of the interval. Record descriptions & results in the table.
Example Table – make the column for the qualitative description the widest

G1 7 thru 11 seconds G2 5 thru 8 seconds
12. Observe the signs on your slopes. What do they represent?
G3 4 thru 12 seconds
13. Using graph 2, compare the speed of both sloped sections. Compare the starting and ending points. If the points are not the same, explain why.
14. Using graph 3, compare the speed of both sloped sections. Compare the starting and ending points. If the points are not the same, explain why.
15. Write a linear equation for the first section of graphs 1 – 3.
16.
What type of motion is occurring when the slope of a distance vs . time graph is zero?
17. What type of motion is occurring when the slope of a distance vs . time graph is a constant (nonzero?)
18. What type of motion is occurring when the slope of a distance vs . time graph is changing?
19. Is it possible to have a vertical line in the position vs. time graph? Explain your answer.
In the end, submit a folder with your last name(s) and containing the 4 Data Studio files that have scores of 90 or above and a Word document with #s 1 - 19 completed. This folder will be placed into the appropriate Drop Box next class. One folder per lab group is an option.
