PASCO


Experimental Setup for PASPORT:

Setup PART 1: Rod with Masses

  1. Connect the PASPORT interface to the USB port of the computer and plug the Rotary Motion Sensor into the interface.

  2. Plug the Force Sensor into the interface.

  3. Attach a rod to a Universal Table Clamp. Clamp it to the edge of a table as in the picture above.

  4. Clamp another rod approximately 75cm from the first rod.

  5. Attach the Rotary Motion Sensor to one rod and the Force Sensor to the other.


  6. Tie one end of a 45 cm length of string to the spring and the other end to the hole of the largest pulley of the 3-Step Pulley as in the picture above.


  7. Place the 3-Step Pulley through the shaft of the Rotary Motion Sensor with the largest pulley facing upward as in the picture above.


  8. Screw the rod to the 3-Step Pulley making sure that the rod rests on the grooves.


  9. Press the "ZERO" button on the Force Sensor.

  10. Attach the other end of the spring to the hook of the Force Sensor.

  11. Adjust the height of the Force Sensor until the hook of the Force Sensor is level to the 3-Step Pulley.

  12. If necessary, adjust the location of one of the rods so that the spring and string are level. It is OK if the spring sags a little.

  13. DOWNLOAD the "Conservation of Energy" DataStudio files:
  14. Open the DataStudio file "ConservationEnergy_PP.ds."

  15. Open the calculator by pressing the button.

  16. Click on the on the right of the window and select the "Rotational Energy" equation.


  17. Highlight, then enter the value of the moment of inertia into the equation as in the picture above. Click .

  18. Click from the menu.


  19. Select the Medium Pulley.

  20. Close the Experiment Setup and Calculator windows.
Go the the Data Collection procedure.

Setup PART 2: Aluminum Disk
  1. Remove the rod with masses by unscrewing it from the 3-Step Pulley.

  2. Invert the 3-Step Pulley and slide it into the shaft of the Rotary Motion Sensor.

  3. Screw the aluminum disk to the top of the 3-Step Pulley.

  4. In order to enter the proper value of the moment of inertia, repeat steps 15-17 from Part 1 of the set up for the aluminum disk.

  5. Repeat steps 18-20 from Part 1 of the set up for the aluminum disk. Select the Large Pulley.
Go the the Data Collection procedure.

Setup PART 3: Disk and Ring
  1. Attach the ring to the top of the disk. Make sure the fittings of the ring fit into the disk

  2. In order to enter the proper value of the moment of inertia, repeat steps 15-17 from Part 1 of the set up for the disk and ring.
