Simple Harmonic Motion Concepts

This video introduces wave behavior in IB Physics, focusing on simple harmonic motion (SHM) as a bridge between mechanics and waves. It reviews kinematics, net forces, and energy concepts, emphasizing periodic motion and its characteristics. The video explains SHM, analyzing mass-spring and pendulum systems, and explores connections to circular motion. It concludes with energy transformations in SHM, highlighting the conservation of mechanical energy and the impact of non-conservative forces.
