Rotating System on Air Bed

The Rotating System on Air Bed is an ideal apparatus for investigating frictionless rotation. Weights can be attached to a cross bar, which is supported by a small, rotating disc complete with a protractor scale. The axis of the disc is centred in a bed of air while a driving weight can be suspended using single and multiple pulley systems. The time of rotation can either be monitored using a hand-held stopwatch or a digital timer connected to the starting mechanism supplied with the kit. This timer can be halted by the laser reflection sensor when the wheel passes through zero.
