Maxwell's Wheel

Product Code : SCL-PLE-10503

The Maxwell's Wheel from Lab Glassware Manufacturer is a physics laboratory apparatus, named after physicist James Clerk Maxwell, used for demonstrating rotational and translational motion, moment of inertia, and energy conversion.

Quick answer: Maxwell's Wheel is a physics apparatus in which a symmetrical wheel unwinds along two cords as it descends, converting potential energy into both translational and rotational kinetic energy, used to study moment of inertia, angular acceleration, and energy conservation in mechanics practicals. It is supplied as a standard physics demonstration apparatus by Lab Glassware Manufacturer; no independent certification is claimed unless separately confirmed in writing.

Demonstrating Energy Conversion with Maxwell's Wheel

As the wheel of this apparatus descends and unwinds along its two supporting cords, its stored potential energy converts into a combination of translational kinetic energy (the wheel moving downward) and rotational kinetic energy (the wheel spinning), making it a classic demonstration of energy conservation across two forms of motion at once. Because the wheel briefly reverses direction and rewinds back up part of its cords once it reaches the bottom, it also illustrates that mechanical energy is conserved (aside from small losses to friction) over a full cycle. This apparatus pairs well with other rotational dynamics equipment such as the Moment of Inertia of Cylinders set for a broader unit on rotational mechanics. Mounting height and cord length should be confirmed for classroom space requirements before ordering.
