The 30 pages that link to Pendulum, each with the reason it gives.

• Galileo GalileiRelated: Galileo studied its regular oscillations, a clue to measuring time.

• Gravitational accelerationRelated: Its period provides a way to estimate local acceleration.

• Gravitational potential energyRelated: Its motion repeatedly trades height-related energy for kinetic energy.

• BrachiationRelated: A brachiator’s body swings beneath each handhold, though active limb motion modifies a simple pendulum’s path.

• InertiaRelated: Its mass resists changes in motion, shaping the timing and swing of the system.

• EscapementRelated: In pendulum clocks, each swing cues the escapement to release a tooth.

• Action-angle variablesRelated: Its librations admit action-angle coordinates, while the separatrix exposes their limits.

• Constraint (mechanics)Related: A fixed-length support constrains the mass to a circular path.

• Elliptic integralRelated: The exact period of a pendulum at finite amplitude is expressed using a first-kind elliptic integral.

• Zhang HengRelated: Later explanations of Zhang Heng’s device often invoke a moving mass, though its exact mechanism is unknown.

• Charles Marie de La CondamineRelated: Pendulum observations during the expedition provided evidence about gravity’s variation with latitude.

• Schiehallion experimentRelated: The pendulum’s alignment provided a practical way to measure the plumb line’s deflection.

• Rocking horseRelated: Both produce repeated motion, though a rocking horse pivots on runners rather than a hanging point.

• TetherballRelated: The tethered ball swings when a strike redirects its motion.

• TiltmeterRelated: Some tiltmeters infer inclination from a mass’s displacement relative to gravity.

• Metre-stickRelated: A metre-stick can measure pendulum length in experiments on oscillation.
