Spin Velocity - Marin - Jul. 22, 2008

Someone and I were talking about this the other day and I wanted to know what you all thought. His question was, why is spin velocity called spin velocity? My interpolation is he meant that velocity is a change in position and thats not what we're trying to refer to in beyblade but I'm not sure about that, I'll ask him later.

My own weigh in; why do we use the term (if it is incorrect) when RPM would be just as acceptable especially since its usually used relatively (that would produce a higher RPM/ that would produce a higher spin velocity), why do we use the term for so many different things? Maximum RPM, potential to retain RPM apparently from the article, but these are totally different things.

Know, I did minimal research on any of this and physics aren't my forté or anything but I thought it might be worth bringing up.

[I hope this is in the right place, I considered posting in the wiki subboard and asking in the "Ask a question" topic but thought it might be interesting/deep enough to warrant a topic and figured it could be moved later anyway if mods deem fit.]

This should be in the "Ask a question, get an answer" forum but I'll answer your question.

RPM stans for "Revolutions Per Minute" meaning how many times from one point of a beyblade it will take to turn once around in a set time. An example is a beyblade has a RPM of 3000, this means from one point it will spin 3000 times in one minute.

Now Spin velocity is a bit different, but is related to RPM. The faster the blade spins the higher the spin velocity. This is related to centrificul force. The more it spins, the more energy the beyblade gives off, making it hevier than others. This is the main principle of some defense/enderance blades.

I hope I answered your question

RE: Spin Velocity - Bey Brad - Jul. 22, 2008

We use it to refer to potential to retain RPM. All Beyblades have the same maximum RPM.

RE: Spin Velocity - Marin - Jul. 22, 2008

Why is it called Spin Velocity when its not Velocity at all (if it is velocity, explain how please, I don't get it)?

I'm not the one who made up the term. If it's proven to be incorrect, I'll correct it.

RE: Spin Velocity - Marin - Jul. 23, 2008

I'll ask my friend when I get a chance, like I said I didn't quite catch his thinking.

RE: Spin Velocity - Nic - Jul. 23, 2008

Urgh, spin velocity isn't even spin velocity. In fact, there's no such thing as spin velocity, since the velocity of a spinning object is 0. It should be called angular speed.

Anyway, in Beyblade context, the usage is slightly different. In normal life (or rather, in physics lectures) we would say that something spinning has a higher angular speed (or "spin velocity") than something that isn't spinning.

But! In beyblade, we can say something like, "Driger S has a higher spin velocity than Wolborg". This is because, when launched under the same conditions, Driger S would tend to spin faster, most of the time.

Let's say you launch both of them at the same strength, or launch them so that they start off spinning at the same speed. However, because of the way their tip contacts the stadium, Driger S maintains the speed better (to quote Brad, "potential to retain RPM").

Hope this clears it up a little.

Edit: By the way, your friend is correct by defining velocity as relating to change in position.

RE: Spin Velocity - Bey Brad - Jul. 23, 2008

So should we change the term to "spin rate" or something?

RE: Spin Velocity - Marin - Jul. 23, 2008

Would it be "potential to retain angular speed" / "potential to retain RPM" / "potential to retain spin [rate]" because again "spin rate" doesn't represent a quantity over time (as in, its a projection of what is happening at that moment as opposed to what is projected to happen in the future)?

I'm afraid I can't be much help here but I hope thats understandable at least. I think its worth changing these terms to be as accurate as possible because A lot of peoples reaction to the game is that its for children (understandably, it is) but they are unwilling to see the technical side of game-play. With the correct terminology, anyone who's worth their salt could clearly see and understand exactly how deep the game is.

Since we've been using "spin velocity" for so long, we might as well just stick to it. Actual science itself is full of misnomers that keep their names for historical reasons.

That's too long a name, it doesn't have the same ring as "spin velocity"

If everyone feels too strongly about this, we could always just say something along the lines of "in battle it has a higher spin rate".

Edit: Thinking about it, let's just call it "spin".

Kenny knows his ****.

I second "spin", for the record. Since 'blades in retrospect all have the same max RPM the wording becomes pretty obvious and it doesn't sound like pseudo-science to people who approach it knowing what the words mean.

RE: Spin Velocity - Bey Brad - Jul. 24, 2008

"Spin" is a pretty ambiguous term and would get pretty confusing being used in articles.

RE: Spin Velocity - Gotruto - Jul. 24, 2008

i call it Rotation-Speed,

RE: Spin Velocity - Marin - Jul. 24, 2008

What about angular speed then.

RE: Spin Velocity - Bey Brad - Jul. 24, 2008

how about "ughhhhhhhhhhhh"

RE: Spin Velocity - Cye Kinomiya - Jul. 24, 2008

I vote spin rate

RE: Spin Velocity - Nic - Jul. 24, 2008

Bey Brad Wrote:how about "ughhhhhhhhhhhh"

I second that. There's no better way to describe how horrible it is to decide on a name for it.

RE: Spin Velocity - Kei - Jul. 24, 2008

Cye Kinomiya Wrote:I vote spin rate
If its really such a big deal, then I vote for spin rate as well.

I think we're all so used to using spin velocity though, everybody understands what it means.

RE: Spin Velocity - Marin - Jul. 24, 2008

But its wrong. Isn't this the same issue with the 8-wide/Eight wide thing? I forget what you guys did in that case, I didn't watch the thread, but its like, why not have the wiki be as accurate as possible.

RE: Spin Velocity - Blue - Jul. 24, 2008

Radian per second ftw. well not really. problem is we can't really use values since we can't measure them easily.
http://en.wikipedia.org/wiki/Radian_per_second

no point in using rpm since that is a max theo. speed. too.
i think though we sould be talking in terms of MOI's. spin rate iz maybe okk.

The point is that we arn't even talking about the exact value. We're talking about relative values, or rather, relative values as a function of time. There's no use saying "My DRIGER ZZXXZZ SPINS AT 50000 RPM!!", what's really important is that in battle, it'll consistently maintain a higher spin rate than the opponent.

I think right now it should be okay. We're using RPM to talk about how fast it's actually spinning (although we never ever talk about it xP), and using "spin velocity", or whatever other terms, to refer to whether it maintains it's speed well or not.

...MOI? Please tell me that you're NOT thinking of moments of inertia.

RE: Spin Velocity - Marin - Jul. 26, 2008

Would it not be worth putting it to a vote with both opinions expressed (historical compatibility versus accuracy I guess, not sure)?
