Choose five different rod lengths between 0.5 and 2.0 meters. Enter the data in the table.
Ensure damping is set to 0, starting angle is 45°, gravity is 9.8 m/s2, and mass of ball is 250 g.
Run the simulation for five seconds by pressing the play button. The simulation will stop at five seconds. From the graph, determine the amount of time it took for the pendulum to complete one cycle. Because the swing is consistent, you can use any consecutive points. Here is an easy way to determine the approximate period:
The two arrows show the start of a cycle (point A) and then the end of the cycle (point B). Choosing where the graph crosses the x-axis is a good reference. Also notice where the end of the cycle is located. You need a complete cycle for the period.
