Which one rolls faster? Customization of science museum exhibitions, campus community science popularization equipment, source manufacturer of science exhibitions, exhibition description and introduction of scientific principles:

Operating instructions: Place two wheels at the high end of each track, then move the operating lever to make both wheels roll down simultaneously. Guess which wheel rolls faster? Function Overview: Exhibitions consist of an operating lever, two tracks of the same length and inclination angle, and two circular wheels of the same size and mass but with different mass distributions. Firstly, place the two wheels at the high end of each track, and then move the operating lever to make both wheels roll down simultaneously. Guess which wheel rolls faster? Upon careful observation, you will notice that the wheel with a mass distribution close to the center of the shaft rolls faster. Why is that? The reason is that the mass distribution of the two wheels is different, and their moment of inertia is also different. The closer the mass distribution of an object is to the center of the axis, the smaller its moment of inertia, and the easier it is to change its rotational state. Therefore, during the process of two wheels rolling down the track from rest, the wheel with the smaller moment of inertia rolls faster than the wheel with the larger moment of inertia. The moment of inertia is an important parameter in industrial fields such as scientific experiments, engineering technology, aerospace, power, machinery, and instrumentation.
