Purpose: PHYS To analyze the motion of a cart down an inclined track using a motion sensor. Apparatus: PC, Interface, Motion Sensor, Dynamics Track, Collision Cart, End Stop, Brass Weight, and Wooden Block. Procedure: 1. Incline the Dynamics Track using the Wooden Block. 2. Attach the Motion Sensor at the 0-cm end and End Stop close to the other end. 3. Place the Collision Cart about 20-cm from the motion sensor and use the Brass Weight to hold the cart in place. 4. Connect the motion sensor to the interface (yellow-1, black-2), set the beam to narrow, and make the detection-surface perpendicular to the track. 5. Open DataStudio, click Create Experiment, scroll down the sensors, and double-click Motion Sensor. 6. Double-click the Graph display, O.K. position data source, and maximize the Position VS. Time graph display. 7. Click Start, and then remove the Brass Weight in order for the cart to roll down and collide with the End Stop. 8. Stop the data collection, and show your data to the instructor.___________ 9. Maximize the Position VS. Time data and obtain the following: a. What is the initial/resting position of the cart?_______________________ b. What is the final position of the cart?_____________________________ c. Describe how the position changes with time between the initial and final positions? (linearly or non-linearly)___________________ d. What is represented by the slope of the Position VS. Time graph?_______________ e. What is the velocity of the cart just before the collision?_______________________
10. Double-click Graph the display, select Velocity data source, and complete the following: a. Describe the features of the Velocity versus Time graph. _______________________________________________________________________ _ _______________________________________________________________________ _ b. What is the maximum velocity of the cart?________________________________ c. How well the above velocity compares to the velocity from Procedure 9e? _______________________________________________________________________ _ d. What is the acceleration of the cart down the track?__________________________ e. Measure the angle of inclination and calculate the acceleration due to gravity. _______________________________________________________________________ _ _______________________________________________________________________ _ 11. Double-click the Graph display, select Acceleration data source, and complete the following: a. Describe the features of the Acceleration versus Time graph. ...
