Flywheel with Counter (25 cm Diameter) is an advanced physics laboratory apparatus designed for accurate study of rotational motion and determination of the moment of inertia of a flywheel. The built-in revolution counter makes the experiment more convenient by allowing precise counting of rotations.

It features a finely machined and dynamically balanced metal flywheel of 25 cm diameter with a 4.4 cm wide rim, mounted on a horizontal steel shaft. The shaft is supported by high-quality ball bearings to ensure smooth and low-friction rotation during the experiment.

A diametric hole is provided in the shaft for attaching the supplied pin and cord arrangement to apply torque. The sturdy base includes mounting holes for secure installation, making the apparatus reliable for regular laboratory use. Supplied complete with cord and hook.

Experimental Objectives

To determine the moment of inertia of a flywheel using rotational motion.
To study the relation between torque, angular acceleration, and moment of inertia.
To measure the number of revolutions accurately using the integrated counter.
To understand energy storage and motion in a rotating rigid body.
