Quick Answer: The Coupled Pendulum is an oscillation apparatus with two pendulums on one support stand, linked so that energy passes from one to the other. Set one swinging and its amplitude slowly falls as the second pendulum picks up the motion.

Key Features
Support stand carrying two pendulum bobs on strings
Coupling connection between the two pendulums
Pendulum lengths adjusted and aligned before each run
Shows energy transfer, resonance, phase difference, beats and normal modes
About This Product
Students displace one pendulum, release it and time how long the energy takes to move across to the other and back, watching the amplitudes rise and fall in turn. Changing the coupling, length or starting displacement, where the model allows, links the observations to normal modes, beats and resonance in coupled oscillators. Laboratories and colleges in Antigua and Barbuda, Bangladesh, Armenia, Bhutan and Qatar can buy the Coupled pendulum through an export order.
Frequently Asked Questions
What does the Coupled Pendulum show?
How two connected pendulums exchange energy: the swing of the first gradually passes to the second and back, showing coupled oscillation, phase difference, beats and normal modes.
