no it doesn't

it does

nope, dont need it

gravity wasn't even proposed until the era of keplar and newton

only because you SAY it does

now proev it

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

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

2 lines

weight

which is shorthand for m*a

force=mass x acceleration for weight

weight is a force measured in n

mass in kg

and weight is in kg

funny that

weight isnt in kg

weight is not kg

E=mc the guy wore womens shoes

kg is mass

when we give weight in kg we divide it by 9.8

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

which is the gravitational field strength

9.81 to be exact

thats what i use in physics

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

your body applies 80KG onto the scale

force is measured in N or kgms-2

therefore your mass is 80*9.8

what?

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

huh

the earth has 9.81

moon i think is 1.6

just a big difference

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

The acceleration is unmodified

huh

thats a big balloon
