Moment of Inertia Disc on Magnet

Plastic disc to demonstrate rotational energy.

  • 6.5" Plastic disc mounted on ball bearing and magnetic base perforated with hole at 1 cm interval on 12 axes at 30°
  • Supplied with 6 moveable pins with attachment holes
  • Use for study of rotational energy
  • Holes drilled in disc allow for manipulation of mass in relation to the axis, thus altering the rotational energy
The Moment of Inertia Disc is an invaluable tool for studying rotational energy. With a powerful magnet it can be affixed to a wall or table for experimentation. The bearing provides the disc with an incredibly smooth, unimpeded rotational movement. Through experiments with this device it is possible to determine and study the torque needed for acceleration on a rotational axis. The unit comes with 6 metal pins with string holes as well as holes drilled throughout the disc to shift mass from one place to another and observe the degree to which rotational energy is affected by the distribution of an objects mass. Consider using with Labs Table Clamp Pulley (PH0297A) for setting up a hanging weight experiment in which the student can observe the moment of inertia and record data accordingly.
