Description of Experiment

• For the Pendulum Experiment, we kept everything
  very organized. First, we gathered all of our
  materials. Then, we swung the pendulum doing 10
  trials for each degree while recording all of our
  data in our journal. I would hold the string from
  up top while holding the timer, then Amanda would
  hold the pendulum at 20 degrees and let it go.
  Then we used the data that we recorded and
  followed the directions on the handout Mr.
  Steaffens gave us.

Materials

• A Metric Ruler
• A String
• A Pendulum
• A Stop Watch
• A Pen and Paper
• An overhead projector

4
Procedure

• Test the period length in seconds for pendulums
  from 6 to 8 different lengths.
• Construct a scatter plot from data.
• Use a graphing calculator to find function.
• Use function to determine time it would take to
  swing 1 mile.

This is the equation of our experiment
I found the equation. He found it during a
tutorial. I plugged random numbers in, first I
did all 5 instead of the current numbers. Then I
changed it to 3s. Then I just messed around with
the numbers.

This is our table that includes the information.
L1 indicates the length of the string. L2
indicates the averages of the seconds.

The Answers

• The function is Linear because it is a constant
  straight line.
• According to my calculations it would take
  approximately 800 seconds for it to swing a mile.
• Yes, there is B and C in our equation. B
  signifies the location of the vertex. C signifies
  the steepness of the graph.
• It would be 1,210.74 cm.
