Makes me think of a flywheel.

The one with a larger moment of inertia will travel further since it releases its built up rotational kinetic energy over a larger period of time.

I don’t think so. I think the one with the lower moment of inertia in theory may travel a bit more due to a bigger acceleration

@@markstice2098 I actually think you are right. The lower inertia wheel will travel further due to its greater speed. More of the energy is being used to move the thing forward rather than spinning it up. kzread.info/dash/bejne/lGuuudmoacfImbg.html

Keep going man, this is cool!

I think the main problem with the original video is you don’t explain why the disc has a lower moment of inertia. You’re basically just pointing to the equation saying “see that’s why” but not actually explaining it. Would be awesome if you showed an intuitive explanation

Woah man you're really underrated

Go sit on a spinny chair, and take the biggest swing you can make with your legs and feet to start spinning with your feet off the ground. First start with your legs stretched out as far as they can go, and then quickly fold your legs inward, going into a partial fetus pose. Notice how you spin faster despite no external force being applied to you after you pulled your legs in? It's the same principle as to the reason why that disk will spin faster.

That's right. Higher inertia = lower speed
