A. Introduction: Data Studio Video
B. An experiment to measure your palm
temperature:
Apparatus: PC, interface, and temperature sensor.
Procedure:
1. Plug in the temperature sensor to analog channel A, white arrow on top.
2. Double-click the DataStudio icon in the desktop.
3. Click Create Experiment.
4. Click Add Sensor, and Scroll down the sensors, and click on the first Temperature
Sensor.
5. Double-click the graph display.
6. Double-click the digit display.
7. Click the start button, after 5 seconds hold the probe, black end, of the
temperature sensor in your palm.
8. Collect the temperature of your palm data for about 60 seconds.
9. Stop the data collection and write down the final temperature.__________
10. Print a hard copy of the graph display.
11. Close DataStudio, by clicking the 'X' in the upper-right corner, and
clicking 'NO' for the question, 'Do you want to save this activity?’.
12. Remove the temperature sensor from the interface.
Apparatus: PC, interface, motion sensor, and meter stick.
Procedure:
1. Connect the motion sensor to digital channels 1 & 2. (Yellow-1 and Black-2)
2. Open DataStudio, Click ‘Create Experiment’, Click ‘Add Sensor’, Select ‘Digital Sensors’, double-click ‘Motion Sensor’ and Click ‘Digits Display’.
3. Place the motion sensor on the lab-table and set the sensor surface parallel to the lab-table surface.
4. Click ‘Start’ and record the sensor reading of the distance to ceiling.
5. Stop the data collection.
6. Measure the above distance with a meter stick and calculate the % difference.
7. Close DataStudio, by clicking the 'X' in the upper-right corner, and clicking 'NO' for the question, 'Do you want to save this activity?’.
DATA:
Sensor reading of the distance to the ceiling = ___________________
Your measured reading of the distance to the ceiling = ______________
% Difference = ______________
D. Acceleration of a free fall:
Apparatus: PC, interface, motion sensor, balls, tall lab-stand, pendulum-clamp, strings, tape, scissors, and plumb-line.
Procedure:
DATA:
Acceleration of the free fall for a rubber ball = ___________________
Acceleration of the free fall for a tennis ball = ___________________
Accepted acceleration due gravity = ___________________
E. MOTION
Purpose: 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 the Graph 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.
________________________________________________________________________
________________________________________________________________________
b. What is the acceleration of the cart down the track?________________________
c. How well the above acceleration compares to the acceleration from
Procedure 10d?
________________________________________________________________________
d. What is the maximum deceleration of the cart during the collision with
the End stop?
______________________
e. If the mass of the cart is 0.5 kg, determine the maximum force exerted by
the End stop in stopping the cart.
