The 300 is more angular.

Even though it's called the angular velocity it tends to be treated as angular speed

So it measures acceleration, angular acceleration

The color for the angular distance measurement ruler.

This is called the conservation of angular momentum.

The other classical cosmological test is the angular diameter test.

The angular momentum spinning up or spinning the other way.

Which you can measure from angular suppression of the sky.

So the speed is equal to the angular velocity times r

Since then we've had WMAP, which just gives us higher angular resolution.

Let's say that the angular velocity is equal to omega radians per second

Now few words about the other classical cosmological test, the angular diameter test.

And if it's going clockwise, the angular velocity vector would pop into the page

I guess we could say the magnitude of the angular velocity times the radius

For those of you who remember your physics, that's a zero angular momentum righting response.

You have to dissipate energy, not the angular momentum get a disk, then make stars.

The other kind of thing that we can measure is the angular size of things.

And this measure of how fast you're orbiting around a central point is called angular velocity

You could say angular velocity is equal to change in angle over a change in time

So it turns out the inertia, which governs angular motion, scales as a fifth power of R.

So this right over here, this 10 pi radians per second we could call this its angular velocity

So as a result, the angular acceleration, denoted by the Greek letter alpha here, goes as 1 over R.

We can measure, roughly speaking, two kinds of things, brightness, from some source far away or its angular size.

And lastly, here's Destin, from Smarter Every Day , talking about the conservation of angular momentum and, since it's YouTube, cats

So our angular velocity, if we want revolutions per second it's going to be omega over 2 pi revolutions per second

large, we can then simplify that get rid of all the, both the angular terms and just have the radial term.

L of 200, or angular scale a little less than one degree, and that corresponds to the size of the horizon.

What's plotted here is the amplitude of projected angular two point correlation function, as a function of depth of the serving.

Likewise, if you are measuring angular diameter test, there is usually a limit to angular resolution, maybe because of the seeing through the atmosphere, and so you're not going to measure anything smaller than a certain level, which will bias your result in that way as well.

A very small angular separations, which will largely be for galaxies that really are physically close together like in clusters or galaxies.
