Physics with Verniers 9 - 1
Calculator 9 3. In the absence of friction and other forces, if you exert a force, F , on a mass, m , the mass will accelerate. If you exert the same force on a mass of 2 m , would you expect the resulting acceleration to be twice as large or half as large? Is this a direct or inverse relationship? PROCEDURE 1. Attach the Force Sensor to a dynamics cart so you can apply a horizontal force to the hook, directed along the sensitive axis of your particular Force Sensor. Next, attach the Accelerometer so the arrow is horizontal and parallel to the direction that the cart will roll. Orient the arrow so that if you pull on the Force Sensor the cart will move in the direction of the arrow. Find the mass of the cart with the Force Sensor and Accelerometer attached. Record the mass in the Data Table. 2. Connect the Low-g Accelerometer to Channel 1 of the LabPro or CBL 2 interface. Connect a Student Force Sensor or Dual-Range Force Sensor to Channel 2 of the interface. If you are using a Dual-Range Force Sensor, set the range switch to 10N (5N on older units). Use the black link cable to connect the interface to the TI Graphing Calculator. Firmly press in the cable ends. 3. Turn on the calculator. Start the DATAMATE program and press CLEAR to reset the program. 4. If CH 1 and CH 2 display the Accelerometer and Force Sensor and their current readings, skip the remainder of this step. If not, set up DATAMATE for the sensors manually. To do this, a. Select SETUP from the main screen. b. Press ENTER to select CH1. c. Choose ACCELEROMETER from the SELECT SENSOR list. d. Choose LOW G ACCEL from the ACCELEROMETER list. e. Press to select CH2 and press ENTER . f. Choose FORCE from the SELECT SENSOR list.
