Briefly explain simple harmonic motion and one common misconception about it.

## Simple Harmonic Motion (SHM) Simple harmonic motion is oscillatory movement where the restoring force is directly proportional to displacement from equilibrium and acts toward that equilibrium position (F = -kx). This creates a sinusoidal pattern of motion over time. Classic examples include a mass on a spring and a pendulum with small angles. ## Common Misconception **"The object moves fastest at the extreme positions of its swing"** In reality, the object moves **fastest at the equilibrium position** (center) and **slowest (zero velocity) at the extremes**. This confuses many because the restoring force is greatest at the extremes, but that's precisely where the object is momentarily stopped before changing direction. Maximum force at the extremes means maximum *acceleration* there, not maximum speed. The speed builds as the object moves toward equilibrium, where all its energy is kinetic.
