Pendulum Motion Diagram - Physics of Simple Harmonic Oscillation #1893227 (License: Personal Use)

This schematic depicts a simple pendulum undergoing oscillatory motion, highlighting the vertical displacement h at the two extreme positions and the central equilibrium point. The solid lines represent the string’s position at extremes, while the dashed curve traces the bob’s trajectory, and the arrow indicates the direction of motion. The black dot denotes the pivot, and colored circles mark the bob’s positions during swing.

Used in educational physics content to explain conservation of energy, simple harmonic motion, and periodic systems; commonly appears in textbooks, online tutorials, and lecture slides targeting high school or undergraduate students.
