Experiment topics: ..
The air-cushioned rotational system is a device system for studying frictionless rotational movements on the following topics::..
Rotational motion: uniform and under constant acceleration
Newton's equations of motion for rotational motion
Moment of inertia and torque
Moment of inertia as determined by experiment
Simple harmonic motion of rotating objects ..
The device system is suitable both for illustrative demonstration and for the development of the physical laws of kinematics and dynamics in student exercises and internships at universities.

Productinformation: ..
A small rotating disc with a protractor scale supports a cross bar to which weights can be attached. The disc is supported by a bed of air in which its axis is centred. A driving weight is suspended from a hook at the end of a string that is passed over a single pulley on one side and a multiple pulley on the other. The rotation is very slow and can be measured using a stopwatch by hand. Alternatively, a digital timer may be used. This can be started by a mechanism that is supplied with the kit and halted by a signal from a laser reflection sensor when the wheel passes through angle zero.
