Day 112: Moment of Inertia Demonstrations

We are exploring moment of inertia from several different perspectives. We’ve felt it experientially, derived equations mathematically, observed its effects, and will measure it experimentally. Today, I performed a simple demonstration of rolling two wheels of equal size and mass but different mass distribution down a slight incline. The wheels experience the same torque and yet clearly accelerate at different rates. It is a simple, but convincing demonstration of the effect of the moment of inertia of an object.
