Simple Pendulum Theory

The following is taken directly from: http://cc.ysu.edu/physics-astro/Report.PDF. According to the Simple Pendulum Theory, the period of a simple pendulum is independent of mass and is dependent on the square root of it's length. The forumla would look something like this: T = 2B%L/g. The T is the period of the pendulum, the L is the length of the pendulum and the g is the acceleration of gravity. Now you can set up a simple test in a laboratory to test this theory. You would place a vertical shaft in the lab table using the receptacle provided to you. A horizontal bar would then be connected to the vertical shaft with a clamp, and a string would be attached to the horizontal bar. A mass is attached to the other end of this string and it's pulled back and let go. It should start a harmonic motion. Now, the time required to complete 30 cycles would be measured with a stopwatch and recorded. You want to do at least three trials if not more for complete accuracy.
