Coupled Pendula

Purpose
To demonstrate that coupled pendula will pass their energy back and forth.
Location
room 146, shelf N4
Description
Begin with both pendula in equilibrium (1st photo), then slowly pull one back and release it (2nd photo). After awhile the swinging pendulum will slow to a stop and all the energy will be in the other pendulum (3rd photo). This back and forth exchange of energy will continue.
