We will use DataStudio to plot and analyze the data. Equipment Needed aty Equipment Needed Qty Force Sensor (CI-6746) Mass Set 1 Motion Sensor (CI-6521A) String 1 m O - --- Balance Pulley w/ Clamp 1 Dynamics Cart 1.2 m Track + Computer Setup 1 . Connect the ScienceWorkshop interface to the computer, turn on the interface. and turn on the computer. 2. Connect the Motion Sensor's phone plugs to Digital Channels I and 2 on the interface. Plug the yellow- banded plug into Digital Channel 1 and the second plug into Digital Channel 2. 3. Connect the DIN plug of the Force Sensor to Analog Channel A. 4. Open DataStudio and choose "Create Experiment". 5. Add the force sensor by clicking on the correct connector on the interface and selecting it from the list (Make sure to pick "Force Sensor". NOT "Force Sensor (student)"). 6. Configure the force sensor so it will display Force. use a 200 Hz sample rate. and set the sensitivity to Med ( 10x). 7. Add the motion sensor. Configure the motion sensor so that it will display only Position and Velocity. and set the sample rate to 20 Hz.( your Instructor will show you) Calibrate the motion sensor ( your instructor will help you).

Q 53 I V Draw 2 | |Read aloud + |5 of 8 | 2 | ED Q |6 97 O Equipment Setup 1. Place the Dynamics Track on a horizontal surface. Level the Dynamics Track by placing the Dynamics Cart on the Dynamics Track. If the cart rolls one way or the other. use the Adjustable Feet at one end of the Dynamics Track to raise or lower that end until the Dynamics Track is Track is level and the cart does not roll one way or the other. MAKE SURE THE TRACK IS LEVEL!! motion sensor force meter O + 2. Attach a pulley to the right end of the Dynamics Track. Place the Motion Sensor at the left end of the track. 3. Carefully measure the masses of the cart and Force Sensor with the triple beam balance, and record the total mass in Data Table #1 (IN KILOGRAMS!). 4. Place the Force Sensor on the accessory tray of the cart. 5. Place the cart on the Dynamics Track so the hook end of the Force Sensor points away from the Motion Sensor. The cart will be pulled away from the sensor. The cart must remain a minimum distance away from the sensor. Remember. the minimum distance from the sensor to its target is 50 cm. Put a mark on the Dynamics Track at the minimum distance from the motion sensor. 5. Use a string that is a little shorter than the length needed to reach the floor when the cart is next to the pulley. Attach one end to the Force Sensor's hook. 7. Tie a loop at the other end of the string. add 100 grams of mass and put the string in the pulley's groove. 8. IMPORTANT - Adjust the height of the pulley so the string is parallel to the Dynamics Track. Your Instructor will walk you through these steps ! The Force sensor needs to be calibrated before running the experiment. Click on the force sensor in the "Experiment Setup" window. 10. Select the "Calibrate Sensors" button. Remove the string from the end of the force sensor. Press the tare button on the force sensor. 11. In the "Calibration Point I". "Standard Value" box. enter 0. Now click "Read from Sensor" for "Calibration Point I" 12. In the "Calibration Point 2". "Standard Value" box, enter -0.98. Hang the 100g (0.98N) mass on the string over the pulley and connect to the force meter hook. Hold the cart so that it doesn't move. Make sure the hanging mass is stationary (not swinging). Click the "Read from Sensor" button for "Calibration Point 2". Click "OK" to close calibration window.

Pull the cart toward the left end of the Dynamics Track but keep the cart at least the minimum distance from the Motion Sensor. Do not let the hanging mass bump into the pulley. 2. Start recording data and then release the cart. 3. Stop data recording when the cart reaches the pulley. 4. Stop the cart before it collides with the pulley. O Analyzing the Data 1. Add position, velocity and force to one graph so they are synchronized in time. Examine the + position versus time and velocity versus time graphs. Do they agree with your predictions? 2. Highlight the part of the velocity vs. time plot that shows the movement of the cart. 3. Select a Lincar curve fit. The slope of the velocity vs. time plot is the average acceleration of the cart. 4. Record the slope of the linear fit in Data Table #1. 5 . Using the measured mass values. calculate and record the theoretical acceleration of the system based on the formula you derived on page 3. Show your work here and record the result in Data Table #1. 6. Look at the graph of Force versus time. To find the average value of the tension during the motion, right click on the graph. and choose statistics. Now select the points that correspond to when the objects where moving. and record the mean value of the tension in Data Table #1.
