Vernier Low - g Accelerometer PRELIMINARY QUESTION S What is the relationship between Force and Acceleration when mass is held constant? Predict the shape Force vs Acceleration graph would have when mass is held constant. PROCEDURE 1. Connect a Dual - Range Force Sensor to Channel 1 on the Vernier computer interface. Connect the Low - g Accelerometer to Channel 2 on the interface.
2. Open the file “09 Newtons Second Law” from the Physics with Vernier folder. 3. Attach the Force Sensor to a dynamics cart so you can apply a hor izontal 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. Accelerometer Force Sensor Experiment 9 9 - 2 Physics with Computers 4. Place the cart on a level surface. Make sure the cart is not moving and click . Check to make sure both sensors are highlighted and click
. Trial I 5. You are now ready to collect force and acceleration data. Grasp the Force Sensor hook. Click and take several seconds to move the cart back and forth on the table. Vary the motion so that both small and large forces are applied. Make sure that your hand is only touching the hook on the Force Sensor and not the Force Sensor or cart body.
