Moment of Inertia Disc on Magnetic Base

This moment of inertia disc is mounted on a ball bearing with a magnetic base, designed for studying rotational energy and the moment of inertia. The 6.5-inch plastic disc is perforated with holes at 1cm intervals along 12 axes at 30-degree increments. Six moveable pins with attachment holes are included. The magnetic base allows the apparatus to be affixed to a wall or table for experimentation. The bearing provides smooth, unimpeded rotational movement, enabling students to investigate torque, angular acceleration, and the relationship between mass distribution and rotational energy.
