Match the Graph Lab
Before starting complete the following procedures to ensure that your labquest is set up properly.
1. One student needs to go to the “Chrome Web Store”...once there search for “Vernier Graphical Analysis” app and install / load
(There will now be a shortcut on the bottom of the screen or you can search for it in your apps whenever you log into a school
Chromebook)
2. Plug the LabQuest Mini into your CB and plug the motion detector into the “Dig 1” port on the LabQuest. The app should
recognize the motion detector and pull up a graph - the detector will start to “click” (also have the motion detector in “cart”
mode - a switch you can see when you flip it open).
3. With the LabQuest use the stylus or finger to click the top left corner, there should be a dial there.
4. Check “Mode” box at the bottom left of screen and check that your settings say: Mode-Time Based, Rate-20 samples/s,
Duration-5.0 s, if not click on these settings to change them.
5. Click the tab towards the top right with the boxes and select “show Graph” and “2 graphs”.
6. Make the top graph a position vs time graph and the bottom one velocity vs time. Click on the y-axis to change it as needed.
7. You should be all set at this point, if you are not sure, check with your teacher.
Directions: Using a LabQuest and a Motion Detector, your task is to create a set-up with your ramp, cart and
motion detector to match the following graphs. You will copy-paste the graphs you made into the doc and
answer questions for each one (we will do one example together).
1. Recreate this position time graph (sketch below how you set up your ramp, cart and motion detector):
2. Use the box in the upper right to view the data table. Select a time frame to analyze and estimate the
acceleration of the cart in this example (I will show you how to do this in the example):
-.45 m/s^2
3. Below, copy and paste an image of the position vs time AND velocity vs time graphs from the app (make
sure you crop the graph so we can see what’s going on - I will show you how in the example).

4. Recreate this position time graph (sketch below how you set up your ramp, cart and motion detector):
5. Select a time frame to analyze and estimate the acceleration of the cart in this example (I will show you
how to do this in the example):
0 m/s^2
6. Below, copy and paste an image of the position vs time AND velocity vs time graphs from the app (make
sure you crop the graph so we can see what’s going on - I will show you how in the example).

7. Recreate this velocity vs time graph (sketch below how you set up your ramp, cart and motion detector):
8. Select a time frame to analyze and estimate the acceleration of the cart in this example (or maybe just say
what you know it to be):
-0.7m/s^2
9. Below, copy and paste an image of the position vs time AND velocity vs time graphs from the app:

10. Recreate this velocity vs time graph (sketch below how you set up your ramp, cart and motion detector):
11. Select a time frame to analyze and estimate the acceleration of the cart in this example:
-5.3 m/s^2
12. Below, copy and paste an image of the position vs time AND velocity vs time graphs from the app:

13. Now that you’ve had some experience, Match the following motions descriptions, position vs time graphs,
and velocity vs time graphs:
Motion Description Position vs Time Graph Velocity vs Time Graph

(enter matching letter) (enter matching letter)
Standing Still a few feet away from

the motion detector.
Moving at a steady pace away

from the motion detector.
Moving at a steady pace towards

Speeding up while going towards

Speeding up while going away

from the motion detector.
Slowing down while going towards

14. Fill in the blanks to create two rules about position vs time graphs and the matching motions using your
observations.
If the graph is__________________________ that means the object is __________________________.
15. Fill in the blanks to create two rules about velocity vs time graphs and the matching motions using your
observations.
16. Each of the 6 motions used here match to both a position and velocity graph. Using the matches and rules
that you’ve made, draw a position and velocity graph for the motion “Slowing down while going away from
the motion detector” which was not listed.
