Formula
Consider a cuboid immersed in a fluid, with one (hence two: top and bottom) of its sides orthogonal to the direction of gravity (assumed constant across the cube's stretch). The fluid will exert a normal force on each face, but only the normal forces on top and bottom will contribute to buoyancy. The pressure difference between the bottom and the top face is directly proportional to the height (difference in depth of submersion). Multiplying the pressure difference by the area of a face gives a net force on the cuboid – the buoyancy, equaling in size the weight of the fluid displaced by the cuboid. By summing up sufficiently many arbitrarily small cuboids this reasoning may be extended to irregular shapes, and so, whatever the shape of the submerged body, the buoyant force is equal to the weight of the displaced fluid.

it is literally the equation f=ma

2019-03-17 16:56:17 UTC  

So you've already mentioned gravity on line one, circular logic

weight

2019-03-17 16:56:38 UTC  

which is shorthand for m*a

2019-03-17 16:56:40 UTC  

force=mass x acceleration for weight

2019-03-17 16:56:59 UTC  

weight is a force measured in n

2019-03-17 16:57:06 UTC  

mass in kg

2019-03-17 16:57:14 UTC  

and weight is in kg

2019-03-17 16:57:15 UTC  

funny that

2019-03-17 16:57:21 UTC  

weight isnt in kg

2019-03-17 16:57:25 UTC  

weight is not kg

2019-03-17 16:57:29 UTC  

E=mc the guy wore womens shoes

2019-03-17 16:57:29 UTC  

kg is mass

2019-03-17 16:57:35 UTC  

when we give weight in kg we divide it by 9.8

2019-03-17 16:57:44 UTC  

So when I stand on the scales I measure my WEIGHT in kg

2019-03-17 16:57:46 UTC  

which is the gravitational field strength

2019-03-17 16:57:53 UTC  

9.81 to be exact

2019-03-17 16:58:15 UTC  

thats what i use in physics

2019-03-17 16:58:17 UTC  

no you measure your mass in kg, its just that weight is the force apllied onto the scale

2019-03-17 16:58:33 UTC  

your body applies 80KG onto the scale

2019-03-17 16:58:48 UTC  

force is measured in N or kgms-2

2019-03-17 16:59:03 UTC  

therefore your mass is 80*9.8

2019-03-17 16:59:25 UTC  

what?

2019-03-17 16:59:25 UTC  

So why does the FORCE always have UNIVERSAL ACCELEATION for all bodies of UNIFORM DENSITY?

2019-03-17 16:59:38 UTC  

huh

2019-03-17 16:59:46 UTC  

the earth has 9.81

2019-03-17 16:59:56 UTC  

moon i think is 1.6

2019-03-17 17:00:03 UTC  

just a big difference

2019-03-17 17:00:14 UTC  

I drop a 1kg lead weight I drop a 1000kg lead weight.
Acceleration down same rate
I drop a 1kg helium balloon I drop a 1000kg helium balloon.
Accelerate up at the same rate

2019-03-17 17:00:22 UTC  

The acceleration is unmodified

2019-03-17 17:00:30 UTC  

huh

2019-03-17 17:00:42 UTC  

thats a big balloon

2019-03-17 17:00:45 UTC  

you only ever observe changes in acceleration

2019-03-17 17:00:51 UTC  

Because of acceleration due to gravity; 9.8111 m/s

2019-03-17 17:00:53 UTC  

While yes when it’s falling it has similar acceleration

2019-03-17 17:01:13 UTC  

Greetings

2019-03-17 17:01:15 UTC  

But that doesn’t prove or disprove anything

2019-03-17 17:01:16 UTC  

They built bigger

Considering gravity is missing in places, we must assume the model is wrong
