SUMMARY
The discussion centers on the concept of resonant frequency as it applies to a pendulum constructed with a light thread and a low-density polystyrene bob. When oscillated at its resonant frequency in a vacuum, the amplitude of the pendulum's motion tends to infinity due to the periodic application of force at the optimal timing. This phenomenon is analogous to pushing a swing at the precise moments to maximize amplitude without disrupting its motion. Understanding this principle is crucial for grasping the mechanics of oscillation and resonance.
