Maxwell Rolling Pendulum Overview The Maxwell Rolling Pendulum is a compact demonstration device that clearly shows the interaction between kinetic energy and potential energy and the conservation of mechanical energy. Its precise motion and durable construction make it suitable for classroom demonstrations, laboratory experiments, and display. Key Features and Benefits Clear demonstration of energy conversion and conservation: Watch the rolling wheel convert potential energy to kinetic energy as it descends, then convert kinetic energy back to potential energy as it climbs, with motion gradually damping to rest. Solid construction for reliable performance: Plasticsprayed steel base provides stability, a chromeplated metal bracket holds the shaft level, and an iron balance wheel delivers consistent rotational behavior. Accurate, repeatable motion: The rolling shaft is threaded and securely fixed at both ends. Suspension wire winds evenly on both sides so the wheel rises and falls with smooth, predictable oscillation. Easy to set up and operate: Mount the shaft on the bracket, twist the shaft by hand to wind the suspension wire and raise the wheel, then release to observe the rolling and rising cycle. No special tools required. Compact footprint for classroom and desktop use: Dimensions 248 x 108 x 405 mm (9.76 x 4.25 x 15.94 in) and a net weight of approximately 1350 g make it easy to place on a demonstration table or lab bench. How it works The device consists of a balance wheel, rolling shaft, base, stand, and beam. Small holes at both ends of the shaft allow the suspension wire to be threaded and fixed. When you twist the shaft, the wire winds on both ends and raises the wheel. Releasing the wheel lets gravity accelerate the wheel downward while it spins, converting potential energy into kinetic energy. At the lowest point the wheel continues to rotate due to inertia and climbs again as the wire unwinds, converting kinetic energy back into potential energy. This cycle repeats with gradually decreasing amplitude until motion stops. Typical Applications School physics lessons and laboratory demonstrations of energy conversion and conservation. Lab equipment for experiments requiring a clear visual example of mechanical energy interchange. Desk display or collectible for educators, students, and enthusiasts interested in classical mechanics.
