Like.
It means that you take the average. That's what the bracket notation <...> means. So the average value of ##v_x^2## is ##<v_x^2>##. And... -
MMike_bb replied to the thread I What does equiprobable mean in the context of thermal motion?."... it would mean that on average..." this сonfused me. What does it mean? Average of components?

Agree.
What exactly you don't understand? Which sentence? I think this description is really straightforward... -
MMike_bb replied to the thread I What does equiprobable mean in the context of thermal motion?.Dale, Herman Trivilino, I'm so grateful for your help!!:smile: I understand now how it works! PS. I found on SE alternative explanation...

Because the x-direction is chosen randomly. It could have been the y-direction that was chosen instead, or indeed any direction.

Here is a more realistic image: The main thing wrong with this image is that it is 2D and this kind of motion happens in 3D, and also...

Yes, with the qualifications stated below. Not if you have a tremendously large number of molecules, which you do. So the chances of...

MMike_bb replied to the thread I What does equiprobable mean in the context of thermal motion?.I found this book because I need in more detail explanation. (In my old school book there was brief description only: "x,y,z are...

MMike_bb replied to the thread I What does equiprobable mean in the context of thermal motion?.This book says that each of vectors has opposite vector because both direction (negative and positive) are equiprobable. It's true, yes?
-
MMike_bb replied to the thread I What does equiprobable mean in the context of thermal motion?.Ok. But in this book it's written that every value of X-component of velocity vectors match with its opposite. Is it wrong?

On average that is true. So the numbers 0.188, 0.268, and -0.456 are randomly distributed from a standard normal distribution, but none...

MMike_bb replied to the thread I What does equiprobable mean in the context of thermal motion?.I understand it. But how is it possible that for Y-axis we have the same figure with arrows?

MMike_bb replied to the thread I What does equiprobable mean in the context of thermal motion?.Russian. School level.

MMike_bb replied to the thread I What does equiprobable mean in the context of thermal motion?.Now I understand you. In this book it's written that one part of molecules (N/2) move in positive direction and another part of...

Informative.
I don’t think those images are good. They give the impression that every molecule is going outward from a single point. They also give...
