and the air is going somewhere? Air has a higher density than a balloon. *G is not needed, the balloon already flies upwards in spite of gravity because its density is less than the density of air.
yes it's flying up
but in order to start moving forward noticeably in the carriage it needs a noticeable difference in atmospheric pressure between the beginning and the end of the carriage
and for that I think it needs a lot of g
>> the pressure will tend to equalise and as soon as the acceleration is gone it'll equalise.
terminology: mass of what? Probably density, after all. Mass is spoken of in relation to a body.
>> Yeah, sure.

As for levelling up, yes, but the ball will still be ahead. And you don't need a huge pressure differential for the ball to lift off your hands either, and you don't fall with g acceleration while standing on the Earth either.
Where did the air go? Air has a higher density than a balloon. >> no need, the balloon's going up in spite of gravity because it's less dense than air.
It seems to me that the density of the balloon is greater than that of the air.
It's going backwards.
I need a smoke.
where is Andrei?
>> he's probably laughing.

haven't been to a parade in a while :)

Just because the light fractions in the centrifuge are closer to the centre doesn't mean they're going to be up in the parade
Just because the lighter fractions in the centrifuge are closer to the centre does not mean that they will break upwards on the parade
Balloons go up in a parade. And at a kid's birthday party, too. (As long as they're filled with helium and not the parents' farts).
Somebody in the next thread was talking about a cool diploma. What's it good for? Turns out it's for answering questions like that. And to mess with a kid's head at school. :)
Who? It's not me.
>> who? It's not me.
Of course not, I didn't mean you :) It's just funny then....
