11th Grade Physics IS ummer Project Walk by Y51jP30


Summer Physics I Packet, Grade 11
Walking a Distance vs. Time Graph

Kinematics is the study of motion.

In this exercise you will literally demonstrate all aspects of linear motion and then
graphically represent what you have demonstrated. The project consists of three parts:

      Develop a plan of motion.
      Execute that plan and measure its results.
      Take those results and create a written deliverable.

The Plan

Write a “plan” on how you will move.

      Walk only along a straight-line path.
      During your walk there must be a least one time where:
          o you are at rest,
          o you change directions,
          o you speed up,
          o you slow down, and
          o you walk at a constant rate in both directions.
      Note for how long you plan to do each motion.

Your plan must describe 30 seconds of motion.

An example of a plan would be:

   I am going to not move for the first 6 seconds, then I will walk forward at a constant
   rate for 6 seconds, I will then walk backwards while speeding-up….

Executing the Plan

You need 31 timing markers. Poker chips are recommended but anything that can be
used as long as it can be marked, is weighted and can be dropped and not be blown away.
Whatever you choose, number your markers from “0” to “31”.

Walk your plan in an open space, driveway, sidewalk, or back-yard.

      Keep time just by counting aloud (1-one thousand, 2 – one thousand, …).
      Mark where you are at the end of each second by dropping your timing marker in

      Figure out some way to drop the chip so that it does not move from the spot where
       it lands.
      Make all motions last at least 6 seconds or longer so that you can see the pattern
       when you graph the motion.
      When you are speeding up you will be tempted to count faster and when you are
       slowing down you will be tempted to count slower. Don’t. To speed up (or slow
       down) don’t try to take more (or fewer) steps in a second, just plan on taking
       larger (or smaller) steps.
      Make sure you speed up while walking. Don’t just suddenly walk faster, but
       instead make each step a little bigger than the last so that with each step you are
       getting faster.

      Create a data table of marker number (which is the equivalent of time) and the
       displacement of each chip.
           o Your point of origin is where the “0” chip is.
           o All distance measurements are from the point of origin. Note that you
              must display all measurement data in standard SI format, i.e. in meters.
              There are approximately 0.31 meters in one linear foot.
           o Be advised that displacement can be negative. If you move behind your
              point of origin, these distances must have a negative sign.

The Written Deliverable

In corporate-speak, a written deliverable is a report. Your deliverable will be typed in a
12-pitch font (Times New Roman, Arial, Calibri) in black ink using 1” margins.

You will include the following:

      A cover page with the title of this project and your name.
      Your plan of motion.
      Your data table showing time versus the displacement.
      A graph showing displacement versus time. You may hand-draw this graph and
       paste it into your report (or as a separate page insert) or use a graphic and/or
       spreadsheet program (Excel) to create your graph and then cut and paste it into the
       report. Please note on the graph each motion element of your plan. Two of these
       elements should demonstrate curved lines (Why?) though if the motion is not
       maintained long enough, it may not be that obvious.
      Describe how each of the different types of motion is represented on the graph.

The assignment will comprise one test grade in Term 1.
