This Maxwell’s pendulum features a 100 mm rigid plastic or metal disk mounted on an 8–10 mm central axle, with a red marker included for visual tracking. The unit is supported by high-strength nylon or cotton strings, adjustable between 300–400 mm, which are symmetrically attached to a horizontal bar. Its frame consists of sturdy aluminum or stainless steel vertical posts and a base equipped with anti-slip rubber feet. Functionally, the device serves to demonstrate rotational inertia, the conservation of energy, and the interplay between linear and angular motion.
