Pendulums come in various forms and varieties. Here we introduce a swinging rod whose pivot could be changed. Does the time period change and how? Could you build a theoretical model, invoking some basic concepts in mechanics and angular motion? This experiment typifies the exercise of observing a natural phenomenon and finding an underlying principle that explains the observation. In the end the prediction and outcomes are compared. Best of luck. No sample results posted this time.
