Phys 151 - BlackBoard Notes: Making a Mathematical Model

Making a Mathematical Model for a Square Pendulum
BlackBoard Notes

======================= Photo - Click for a Larger Version =============================

======================= First Board Section =============================

Determine the model that describes the behavior of the system, and then put the model to the test
How does the period, T of a square pendulum depend on the length of a side, L?

======================= Second Board Section =============================

Place pendula on bench so that the pin hangs over the edge of the table
What are you plotting today? (span bottoms of second and third board sections)

{Where <T> ≡ Average Period}

======================= Third Board Section =============================

======== Fourth Board Section - if this follows Finding Best-Fit Function Lab! ==============

Last Week: What are the units of residuals? (draw axes for residuals vs. time graph)
(If needed:) Data Sets 2 and 3:
- y = a·e^b·x = a·b^x
- Both are the same because b^x = e^ln(b)x
  - ...but the value of b is different!
