why does a helium balloon rises?

The stresses

Because helium is less dense than air

👍

why does a stone fall

And it rises to a certain altitude and then it stops rising

So its still attracted to the earth

Drop a helium balloon in a vacuum chamber and it falls

because the density of the small rubber is bigger then the full balloon

dude

space is a vacuum is the third debate you're mixing in

The rubber falls back down dude helium balloons expand like crazy

And then they burst

why does a stone fall?

Because it has weight

so why does there have to be gravity?

it's object vs surrounding

Because weight is mass times gravity

You wouldn’t have any weight without it

dude what gravity, you just said thing rise or fall because of density

No i didn’t

I said weight

or weight

Its not the same lol

meh

No really

weight, mass, density

Yes

can be confusing yes

but dude

it's a useless debate

And object can be less dense but have more mass

if done many of these I tell ya...

Then a denser object with less mass

Gravity wise

yeah I get that

And the mass is used to calculate the weight not the density

and if you operate underwater objects behave different again

Fun fact about water

because it's object vs surrounding, no magical centre force pull needed

There’s a pressure gradiant and a density gradiant
