Simple Pendulum Objective We are experimenting with a simple pendulum, swinging through a photo-gate. We would like to determine which properties of the pendulum affect its period. Exercise 1: What Makes the Pendulum Tick? There are basically three main components to the assembly of a pendulum. These are the string length, the starting angle, and the pendulum mass. But which of these affects the overall period? To test the theory, we set up three different experiments, each testing one variable and keeping the others constant. Each experiment was completed using four different variable values, each measuring four period values. The data is shown below. Exercise 1: Period as a Function of Angle Exercise 1: Period as a Function of Length Trial Mass (kg) Length (m) Angle Period (s) Trial Mass (kg) Length (m) Angle Period (s) 1 0.0313 0.515 45 1.5275 1 0.0313 0.515 30 1.4913 2 0.0313 0.515 45 1.5256 2 0.0313 0.515 30 1.4908 3 0.0313 0.515 45 1.5237 3 0.0313 0.515 30 1.4908 4 0.0313 0.515 45 1.5223 4 0.0313 0.515 30 1.49 Average 0.0313 0.515 45 1.524775 Average 0.0313 0.515 30 1.490725 Deviatio n 0 0 0 0.0022648 Deviation 0 0 0 0.0005377 1 0.0313 0.515 30 1.4913 1 0.0313 0.47 30 1.4249 2 0.0313 0.515 30 1.4908 2 0.0313 0.47 30 1.4244 3 0.0313 0.515 30 1.4908 3 0.0313 0.47
