Simple Harmonic Motion Concepts

Professor Anderson introduces simple harmonic motion, a fundamental concept in physics and science. He explains the basic model using a spring and discusses its graphical representation. The lecture delves into the mathematical derivation of simple harmonic motion using Hooke's law and explores the role of differential equations in understanding this motion. The session concludes with a discussion on sinusoidal curves and their significance in modeling motion.
