Main Question or Discussion Point

I thought moment of inertia depends on mass of the object and also its shape. But prof Lewin says it doesnt depend on mass. See this video:

No, he does not say that.

This doesn't regard the inertial moment much.

He says no such thing, You've wasted fifteen minutes of my time. I hope you got your laughs from that.

Not quite. He does demonstrate that the acceleration does not depend on the mass.

Not even sure he mentions the term 'moment of inertia' at all in that video.

This is so funny! On the assumption that every post deserves some sort of response..Dont read this. Sorry.. Too late
But seriously, does your 15 minutes 'wasted' time include the time needed to make your post?

No, just watching the 15 minute video.

You should have told him that the answer to his question is somewhere in the folloing lecture:

I don't think this thread serves any purpose any more. It should probably be closed or moved out of view.
