Coupled Pendulums

Topics: Mechanics - Acceleration, Momentum

Equipment: Two pendulums, spring, rod, stand

Setup: Move one pendulum and observe as the other pendulum begins to oscillate. The level where the two pendulums are coupled can be changed by lifting the black knob on the side of the spring.

The speed of transformation depends on the position of the spring. If the spring is placed higher, the transfer of energy occurs more quickly because of the tendency of a pendulum to oscillate more quickly when its length is shorter. See demo listed as “Pendulums” for more details.
