Section 16.3 Assignment
For this assignment you are to find a safe place to accelerate and decelerate your vehicle while recording acceleration data on the Circuit Playground. I also want you to take GPS data using PhyPhox so you can compare data. I suggest using a temporary adhesive to secure your CPX/CPB to your dashboard (making sure it’s level) and have a passenger in the car to help you record data as well as operate Phyphox and verify that you have a GPS lock. For safety’s sake I suggest finding an empty parking lot and only accelerating to 20 mph or less.
-
Title page with name,title and date - 5%
-
Introduction - 5%
-
All figures must have appropriate annotations, figure captions, figure labels and a paragraph of supporting text - 10%
-
Include a picture of your car and your passenger that is helping you record data. In your description write what speed you achieved in your experiment (If your passenger is in this class you must do the experiment twice and get two different individual sets of data). - 10%
-
Include a photo of your CPX/CPB mounted to your vehicle indicating which axis of acceleration is pointing forward - 10%
-
Plot one axis of your accelerometer data vs time which clearly indicates when you accelerated and decelerated. In your description be sure to explain which axis you are plotting and any signal conditioners you applied to get your clean signal (Again, if your passenger is also taking this class, you must do the experiment twice and get two different individual/unique sets of data).. - 20%
-
Integrate acceleration and plot velocity as a function of time. Comment on whether or not the maximum velocity is the same as what you did in your actual car. Make sure to superimpose your Phyphox GPS speed on top of your plot to compare. You may need to have your raw GPS coordinates converted to velocity if it doesn’t log speed natively. - 20%
-
Integrate the velocity and compute position. Plot your position as a function of time and include that in your report. Also include the position of your car using your GPS coordinates keeping in mind that you may need to convert your Lat/Lon coordinates to meters. Although you didn’t measure how far you went, comment on the accuracy of the plot and whether or not you think you traveled that far especially given the superimposed data from your GPS. - 20%
-
Appendix A - Video Details - Include 2 videos: The first is of yourself and your passenger in the car taking data showing the Plotter open in Mu, the second is plotting the acceleration data and converting that to velocity (Note, if your partner is in this class they must submit their own videos with their own data). - Pass/Fail
-
Appendix B - Code used to take data and code used to plot in plain text (no screenshots) - Pass/Fail
-
Appendix C - Screenshot of Excel or Sheets if applicable - Pass/Fail
-
If you are asked to fix something in the Appendices such as missing content in your video or screenshots of your code, you will lose 10% of your grade everytime you submit an update after the deadline.
