Unformatted text preview: Lab 2: The Simple Pendulum SAR Physics Andrew M Kolchin We’ve been studying the behavior of the Simple Pendulum from a concep- tual point of view for the last few days of class. If you’ll remember, I listed the parameters that define the construction and characteristics of the simple pendulum: 1. θ = the maximum angle of deflection (measured in degrees). 2. L = the length of the pendulum (that is, length of the string) (mea- sured in meters). 3. m = the mass of the pendulum (that is, mass of the ball) (measured in kg). The time it takes for the mass to make one round trip from its initial starting point to the far turning point and back is called the period , expressed by the symbol: T . The units of T are seconds . In this experiment, we’re going to investigate how the period of a pendulum depends on its parameters. To measure the period of a pendulum, you will time how long it takes for the mass to make 20 round trips (using a stopwatch) and then divide this time by 20....
