Idk how people talk about Archimedes principal when it is defined in terms of weight, and weight is itself a force
Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces and acts in the upward direction at the center of mass of the displaced fluid.
a simple experiment in a centrifuge will show applying more force will cause a solution of solvents of different densities to separate faster
🤷
showing how Archimedes principal requires a force to actually work
I'm sure you could design some free fall experiments with rapidly sedimenting objects in a solution to show this, but it should be obvious. In free fall the solution will kind of just fall and wobble about all at the same rate, not separating
or any acceleration, as your centrifuge shows
and you can define a force for any movement
but it doesn't require the theory of gravity
@raspberry yes and I have heard people say gravity can instead be explained by Archimedes principal which I was trying to show as not really making sense
but, just saying, you don't need gravity to have the fact that things fall
hm? that sounds like 2nd law of thermodynamics, instead of buoyancy
well they are related
ok now i think i see what you're saying. the pressure gradient of earth's atmosphere, i think that'd be a result of buoyancy bork
i guess things fall, then that causes buoyancy and the atmosphere's pressure gradient, and all wheter or not there's a globe and gravity
most people say buoyancy completely ignoring the pretty much indisputable fact that buoyancy acts under the assumption of a force
@raspberry What does buoyancy have to do with increasing entropy?

What cat said
one person told me we could also be spinning in a circle and gravity is actually a mix of gravity and acceleration from centripetal force
Hey Demon! @demonwarrior2266
the acceleration change would near match that of gravity
like up at mt everest
you guys steadily coming over to the dark side, huh? yup, there's actual debates to be had here.
yeah but im saying the one person said the whole earth is flat and spinning about a point really fast
they probably just claim it doesn't exist.
as radius (height increases) decreases force actually decreases
they do undeniably
I like arguing just about Newton's laws...
like usually people will say something contradictory to them
And I will just go ????
*"have you been there?"*
relativity is that one topic noone either sides dares to try to explain
Well
cue 97 Eleven
globe model has it down pretty well lol
It's just your average person here hasn't seen relativity outside of an undergraduate physics setting
