Coupled Pendulum Model STEM Lab Manufacturer,Supplier and Exporter in India
Product Code : SCL-MH-12525
Quick Answer: The Coupled Pendulum Model STEM Lab hangs two identical pendulums from an anodised aluminium gantry and links them with a light helical spring, so energy can be seen passing from one to the other. Angle protractors graduated 0° to 45° are built in.

About This Product
Pulling both bobs to 15° on the same side and releasing them together gives the in-phase mode, where the spring stays slack; setting one at +15° and the other at -15° gives the faster out-of-phase mode. Starting one pendulum at 20° with the other at rest shows energy moving across the spring until the first stops briefly, and timing these standstills gives the beat period of the system.
Frequently Asked Questions
How are beats shown on the Coupled Pendulum Model STEM Lab?
Hold one pendulum at rest, swing the other from 20° and release it; energy passes through the spring back and forth, and the time between standstills of the first pendulum gives the beat period.
