Graphing Motion of Boat

Graphing Motion of Rowboats

Purpose:

In this activity you will be testing out my new program for generating motion graphs.

Procedure:

Part 1:  Tracking Motion of the Row Boat

  1. Open the program found here in a new tab.

  2. Click on the paddle button to set the initial parameters for your experiment.  You are free to pick any combination of variables, except at this point I want the current set at none.

  3. In your lab book, set up a data table that will have position of the boat and time.  When you graph, I want you to put time on the x-axis, so you data table should probably look like this:



  4. Return to Cooper River (Thanks Mark) and then click start.  The timer will start immediately even though Eileen has not yet reached the start line of the race course.  When you record your time values, you want to record the displayed time of total time on the water.  So at position 0 m, your time will NOT be zero.

  5. Pause the program when the nose of the boat hits each of the designated distances in the table above.  Record the time as displayed on the program.

  6. When you are done collecting your data, make a plot of Position vs. Time.  Make sure you record both the slope and y-intercpt of your graph.  Then write the equation for your graph in your lab book.
Part 2:  Changing one parameter.
  1. For this part of the lab, you will be picking one and only one of the paddling parameters and running multiple trials to see how this parameter affects the slope of the boat's graph.  Make sure all your other parameters remain constant for the rest of this lab.

  2. Your data table should look something like the one shown below.  But instead of the letters A, B, C and D, put some description of your trial.  Like Gentle Current or Herculean Paddling or 0.5 s Paddle Period or 100 kg mass.



  3. After you have collected data for all four trials, make a graph in Logger Pro with 4 different data sets.  Make sure all your data is displayed on one graph and that your graph is properly labeled.  If you don't remember how to graph multiple datasets, watch this video.

    Multiple Data Sets



  4. When you are done, copy your graph into your lab book.  Make sure each line is labeled and has an equation affixed to it.

  5. Finally, save your graph into dropbox, stuff for students, and make sure that your name and the name of your lab partners are a part of the file name.

Things to have in your lab book:

  • Purpose
     
  • Two Data Tables

  • Two Graphs

  • Your graph saved in dropbox with your name as the filename.
