The Barton's pendulums experiment demonstrates how pendulums respond to vibration at, below, and above their resonant frequencies.
Notes on verification
Multiple independent university physics education sources (Maryland, Harvard, Iowa, Schoolphysics) confirm the purpose and mechanics of the Barton's pendulums demonstration. [tier=silver indep_score=0.938 clusters=4 claim_tier=everyday]
