spin angular momentum

I'll give it a little bit more spin angular momentum, so now I move my left hand towards me and my. . .

The spin angular momentum is now in this direction, so I'm going to give it a torque like so.

If I put it on this side, torque is now in this direction, spin angular momentum is in this direction.

And as long as I torque it like this, that spin angular momentum wants to go around in the horizontal plane.

The angular momentum of light includes spin angular momentum and orbital angular momentum.

I'm going to spin it with a high angular momentum, high spin angular momentum.

I've changed the direction of the spin angular momentum.

Angular momentum has two key components: spin angular momentum and orbital angular momentum.

So this was originally the spin angular momentum of the wheel.

Torque is in this direction; spin angular momentum's in this direction.

A quantum number expressing spin angular momentum.

We have here the spin angular momentum that you saw.

But notice that L, the spin angular momentum, has moved from here to here.

So spin angular momentum has the property of stabilizing things.

The spin angular momentum is chasing the torque.

And what does the spin angular momentum do?

What will the spin angular momentum do?

That's a spin angular momentum.

So the torque is persuading the spin angular momentum to change.

Look at that spin angular momentum.
