To do this experiment you will need a few other people,tape measurer,masking tape, stop watch, electronic walkway,pen and paper. A calculater may be helpful as well.

The point of this experiment is to have fun with the formula d = r t.

Measure the length of the walkway and record it. Now use your stop watch and record the time it takes you to get to the other end of the walkway-be precise when starting and stoping the watch. Repeat the procedure and have the others do the same thing you did.

Here is a look at my example. I suggest you make a chart too.

The distance of the walkway my class used was (D) 279' 10.5". Then converted into feet gives 279.875 feet. Remember there are 12" in a foot.

I had 11 time measurements in my experiment.

       time in seconds
                  137.78
                  138.70
                  138.40
                  138.27
                  138.15
                  138.71
                  137.44
                  138.2
                  138.34
                  137.99
                  138.15

The total is 1520.13.

The average time is 138.2 seconds.

Now plug in and check d = 279.875 feet = r(ft/sec)138.2(sec)

So r = 2.03 feet per second.

That is equal to 24.13 inches per second.
