In the Barton's pendulums experiment, pendulums other than the target pendulum do not move as much, demonstrating that torquing a pendulum at its resonance frequency is most efficient.
Notes on verification
Confirmed by multiple independent university physics demonstration sources (Maryland, Harvard, UCSB) and independent physics tutorials, all consistent with standard resonance theory. [tier=silver indep_score=0.9 clusters=5 claim_tier=notable]
