2.Assume that you have a bowling ball and a baseball, each suspended from a different rope. If you hit each of these balls with a full swing of a baseball bat, which ball will change its motion by the greater amount? 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? Physics with Vernier 9 - 1

Experiment 9 PROCEDURE 1. Open the Experiment 9 folder from Physics with Vernier . Then open the experiment file that matches the force sensor you are using. Three graphs will appear on the screen, as shown in Figure 2. Figure 2 2. Connect a Student Force Sensor or Dual-Range Force Sensor to Channel 1 on the LabPro or Universal Lab Interface. (If you are using a Force Probe, connect the probe to PORT 1 .) Connect the 3-axis Accelerometer to Channel 2 on the interface. 3. To get the best numerical results in the experiment, you will calibrate both sensors. a. Choose Calibrate from the Experiment menu. b. Click the Force icon that appears in Channel 1. (If you are using the ULI Force Probe, click the icon in PORT 1 .) c. Click the button. d. Remove all weight from the Force Sensor and hold it vertically with the hook pointed down. e. Type 0 in the Value 1 edit box. f. When the displayed voltage reading for Input 1 stabilizes, click Keep . g. Add the 0.500 kg (4.9-N) mass to the hook of the Force Sensor. h. Type 4.9 in the Value 2 edit box. i. When the displayed voltage reading for Input 1 stabilizes, click Keep . 4. Click the Acceleration icon that appears in Channel 2. a. Click the button. b. Point the arrow on the Accelerometer straight down. (It is important that the sensor is vertical and held steady. You may want to hold the sensor against a table top to steady it.) c. Type – 9.8 in the Value 1 edit box.
