The information, the artistry, and the genuine effort to provide a clear, concise explanation to this issue inspires me to be a better person, let alone a better student... Hope this guy has a hot wife and good friends; he clearly deserves it.

Short and sweet. Looks good! (I also agree that this qualifies to sing for the song.)

Nearly forgot all about the PAT. One of my favorite physics subjects was rotational inertia! College Engineering physics was when I realized real life wizards exist. You watch a fella change the direction of a spinning chair just by turning a spinning bike wheel over and you’ll reach the same conclusion!

Thank you so much learning with you is really interesting...

Is this supposed to be apart of the AP Physics 1 curriculum? I saw it was on the website for AP Physics 1

Hi you might be able to help me out with something i cant figure out:

If I apply the parallel axis theorem to a (non-spinning) body of mass m in uniform circular motion around a point a distance r away, then I get the angular momentum of the body about the point is
(I + mr^2) omega where I is the body's moment of inertia around its COM and omega is the body's angular velocity around the point.

However if we compute the angular momentum by just getting the orbital angular momentum about the point (where the body isn't spinning around its COM), we get r × mv = (mr^2 omega) which is clearly different to what we got above.

Can you point out where I might be making a mistake here.
Your help is greatly appreciated.
Thanks.

Why does this video and the one with the Parallel axis theorem only have ca. 20-25 Views in one month? It is not listed in your videos when clicking on your channel..., too?

I have a question, will I(cm) be given because I know how to find the center of mass but I’m certain different objects have different moments of inertia.

I have a question.... How many people commented on this video 2 months before, while you have uploaded it 13 hours ago?
