Question about the difference in ball size

[Girthang]

... between the college and NBA level...

Which level has bigger balls?

That other thread just begged the question. Anyone here know?

29.5, for nba and men's college. The only thing that varies is the brands recommended psi.

Same size. HS is the same. Girls balls are smaller.
That would be crazy if every level of Basketball had a different sized ball.

Plus the 22 ounce standard weight. That's why psi differs, more or less.

Did not know that. Thank you

Football hasn't suffered from having a non-universal ball size.

PSI doesn’t affect the weight. 😆

Mass is mass, with or without gravity. Js

Same size, I have seen a women's team saying that they used a men's ball for their game is why they lost but can't confirm it.
They are some rumors that the air pressure has been to high in some games but again no way to prove it.

More air pressure bigger ball not a bunch but a bit.

For another tidbit. The standard is 10% of affected mass per basketball brand. That's why there is a psi recommendation. It's ok that you didn't know though.

I also didn't know that thanks for sharing.

Wrong, I'm sorry. Mass is mass. Air increases mass. Can't argue me Wrong. Science been around awhile now.

Right I would think just the dimensions to a point and the amount of bounce.

It's simple, u deflate a basketball lower than recommended psi. It's going to weigh significantly less. Granted in that range of recommended there will be small variance. But helium tests are done to measure bball quality. I'm not sure what this poster^ up there is trying to gain. But 22 ounces has to be reached. Let's both of us make a basketball company, and recommend our customers 7.5-8.5 psi. While the other recommendations are 1-8.5psi. I got balls that recommended to be 9-9.5 lol

So if you have have 30 PSI in a tire and increase it to 50 psi it weighs 20 lbs more?

It doesn’t. It won’t weigh 1 oz more.

Don’t believe it? Get a frickin

It’s not going to weigh different.

A flat basketball will weigh exactly the same as an inflated ball.

I never said it affects with great margins. But it does affect weight. You are saying psi doesn't affect mass. Mass is weight

 

[crxohio]

We are talking ounces and the fractions that come with it. A deflated bball will not weigh the same as a fully recommended bball. If it's just .01, .02, .03. There is the whole byonuacy side. Etc

Just weigh one then. Weigh a flat ball. Inflate it and weigh again.

It will weigh exactly the same.

Buyonacy my good cat fan. Deflate will sink alot lower than a fully inflated. I'm giving this rest and going to watch the game.
