Experimental Setup for the ScienceWorkshop 750 Interface using DataStudio:
    1. Connect the 750 Interface to the serial or SCSI or USB port of the computer and plug the Motion Sensor into digital channels 1 and 2 (yellow in 1; black in 2).
    2. Attach one end of the track to the rod stand. Raise this end 5.0 to 8.0 cm higher than the other end.
    3. Attach a Motion Sensor to the raised end of the track as in Picture 1 below.
    1. Make sure the motion sensor points parallel to the track as in the picture below. It is also a good idea to have the plunger sticking out and pointing down the track.
    1. Set the switch on the top of the Motion Sensor to "cart" or "near" as shown below.
    1. Press the Calculate button at the top of the DataStudio screen. Press the equation drop down menu and select the KE equation. Measure the mass of your cart in kilograms and enter this value next to the mass or "m" variable. Press the Accept button. See the screenshot below.
    1. While still in the Calculator dialog box, press the equation drop down menu and select the PE equation. Once again, enter the value of the cart's mass next to the mass or "m" variable. Enter the value for the acceleration due to gravity (in m/s/s) next to the "g" variable. Measure the VERTICAL height in METERS that the cart will travel. Enter that value next to the height or "h" variable. Measure the length of track that the cart will travel. Enter that value next to the length or "l" variable. Press the Accept button. Close the Calculator window. See the screenshot below.
    1. Download the "Inclined to Conserve" DataStudio file:
          Windows (Zip file) or Macintosh (Stuffit file).
You are now ready to begin collecting data.
