Quick Answer: The Device to Study Rotational Motion is a mechanics apparatus for experiments on bodies turning about a fixed axis. Masses are set at chosen positions on the rotating part so students can see how mass, radius and speed affect angular velocity, torque and moment of inertia.

Key Features
Rotating part on a spindle and support base
Mass holders with adjustable positions where the model allows
Measuring scale for setting the radius
Covers angular velocity, angular acceleration, torque, moment of inertia and centripetal force
About This Product
Students fix masses at a set radius, start the rotation slowly and note how the motion changes when the mass, its position or the speed is altered. A timer, tachometer or sensor can be added for measurements. The device must come to a complete stop before any part is adjusted or removed.
Frequently Asked Questions
What can be changed in rotational motion experiments with this device?
The mass, its radius or position on the rotating part, and the speed of rotation, so their effects can be compared.
