it could be infinitely less
as long as the ratio stays the same...
Which it obviously does if the helium balloons are identical.
Air has a density of about 1.2kg/m^3, however helium at room temperature at standard air pressure is about 0.164kg/m^3 and hydrogen is lower about 0.1kg/m^3
So for each meter cubed of helium you are adding you can lift about 1kg
Are we changing the subject ok then
So when you have about 100 m^3 of helium you should be able to lift a man
Which law is this?
Archimdedes principle
First law
We are still one that?
F = pVg
p = density
V = volume
g = gravity
Can you really lift a man?
@Ivan Pavlovich What's gravity?
1. CHANGING THE DENSITY OF THE BODY: https://imgur.com/a/uIY067X
all flight is based on lift
No it's not
And what would that be please?
most that is
Downwards force, as pointed out in the diagram you posted
Yeah Archimedes didn't use gravity
So I don't know what your point is
See that downwards arrow?
tbh me neither
ignore that
See that upwards arrow?
Yes.
Yeah exactly
So you admit to a downwards force and a normal force?
So as you can see you can modify the direction and rate of acceleration by changing your density
@Ivan Pavlovich force is mass times acceleration is it?
yes?
NET acceleration
What does this have to do with balloons and more importantly gravity
@Hamburger Guy what's gravity?
If that upwards arrow overpowers the downwards, you will float.
