-Purpose:
•Collect distance, velocity, and acceleration data as a cart rolls up and down a ramp.
•Analyze the position vs. time, velocity vs. time, and acceleration
vs. time graphs.
•Determine the best fit equations for the distance vs. time and velocity vs. time graphs.
•Determine the mean acceleration from the acceleration vs. time
graph.
-Equipment:
Cart, Ramp, Blocker, LabQuest, Stilts for the ramp, Motion Detector
-Procedure:
1. Prepare the track and Motion Detector for data collection.
a. Attach the Motion Detector Bracket to the track (see Figure)
b. Attach the Motion Detector to the Motion Detector Bracket.
c. Adjust the position of the Motion Detector Bracket so the Motion Detector is 0.15 m from the end of the track.
d. Set the switch on the Motion Detector to the Track position.
2. Connect the Motion Detector to DIG 1
of LabQuest and choose New from the File menu.
3. Place the cart on the track near the
bottom end stop. If your cart has a plunger, face the plunger away from the Motion Detector. Start data collection. You
will notice a clicking sound from the Motion Detector. Wait about a second, then briefly push the cart up the ramp, letting it roll freely up nearly to the top, and then back down. Catch the cart as it nears the end stop.
4. Examine the position vs. time graph. Repeat Step 3 if your position vs. time graph does not show an area of smoothly changing distance. Check with your instructor if you are not sure whether you need to repeat data collection.

-Conclusion: In this lab we learned how the graphs of Acceleration, Velocity, and Position vs Time looked and formed by rolling a car up down a ramp.
-Questions:
1. The slope and acceleration was between 0.03 points away from each other each time.
2. (4, 0.566)
3. (1.45, 0.46)
4. Yes
5. N. The graph don't look anything alike.
6. The slope stands for the acceleration. Y stands for velocity. 0.50 is the position.
7. Position: The graph would be a straight diagonal line.
Velocity: The graph would be a straight diagonal line.
Acceleration: The graph would be a straight horizontal line.
