AP Physics 1: Review of Simple Harmonic Motion

The video tutorial covers simple harmonic motion, focusing on a mass-spring system on a frictionless surface. It explains the concepts of equilibrium, restoring force, and amplitude, and applies Newton's laws to analyze motion and forces. The tutorial relates circular motion to simple harmonic motion, exploring angular velocity and frequency. It discusses energy conservation, examining kinetic and potential energy in the system. The video also explains the period and frequency of mass-spring systems and pendulums, considering the effects of gravity and mass. Finally, it concludes with a summary and introduces the next topic on waves.
