Physics Labs with Computers, Vol. 1Student WorkbookP12: Newton's Third Law - Collision and Tug-of-War 012-07000APART I: Computer Setup1. Connect the interface to the computer, turn on the interface,and turn on the computer.2. Connect one Force Sensor DIN plug to Analog Channel A onthe interface, and the other Force Sensor DIN plug to AnalogChannel B.3.

Read the instructions in the Workbook.• The ScienceWorkshop document has a Graph display with two plots of Force versus Timeand Meter displays of Force for each Force Sensor.• Data recording is set at 100 Hz.• The sensors are calibrated so that the Force Sensor connected to Analog Channel B willreact in the opposite way as the Force Sensor connected to Analog Channel A. Forexample, a pull will be a negative force for Sensor A and a pull will be a positive force forSensor B.PART II: Sensor Calibration and Equipment Setup• To calibrate the Force Sensor, refer to the description in the Force Sensor Manual. Whencalibrating the Channel B Force Sensor, enter a positive force for a pull.1. Place the Dynamics Track on a horizontal surface. Level the Dynamics Track by placingthe Dynamics Cart on the Dynamics Track. If the cart rolls one way or the other, use theAdjustable Feet at one end of the Dynamics Track to raise or lower that end until theDynamics Track is level and the cart does not roll one way or the other.2. Use the thumbscrew that comes with the Force Sensor to mount the sensor onto theaccessory tray of each cart.3. Place the carts on the track so that the hooks on the Force Sensors face each other.4. Unscrew the hook attachments from the front of each of the Force Sensors. In their place,put the magnetic collision bumpers from the Accessory Bracket with Bumpers.p. 78 ©1999 PASCO scientific P12
