Product Information

This adjustable double pendulum unit allows you to simultaneously compare the periods of two drilled steel balls with individual string lengths up to 80 cm.
The novel mount fastens to a ring stand and allows the length to be easily changed while the bob is swinging.
Excellent for performing qualitative studies of period, frequency and beats. A stop watch is required to examine these concepts quantitatively (stopwatch not included).
Includes: instructions.
