Gravity's Effect on Buoyant Force

[Sleepy_Sentry]

Hello,

In my 8th grade science class, we are learning about buoyant force. I was wondering what effect gravity had on buoyant force. If gravity increased, would buoyant force decrease? If gravity decreased, would the buoyant force increase?

Thanks a lot and I'm sorry if I posted this in the wrong section.

The buoyant force is equal to the amount of the fluid displaced bt the object.
What happened to the weight of the displaced fluid if the gravity changed?
(If there is no gravity, there is no buoyant force!)

Thanks a lot for the reply.

I know buoyant force is equal to the [i:caed559a75]weight[/i:caed559a75] of the fluid or gas displaced but is there a way to find either of these? I have come to the conclusion that Force = Weight of the column of fluid above the surface area. Is this true and how so?

[Fu-Kwun Hwang]

Buoyant force is equal to the weight of the fluid displaced.
It is not necessary equal to Weight of the column of fluid above the surface area.

I think buoyant force is against gravity..

Buoyant force is against gravity - that's what I thought too.. 

[Fu-Kwun Hwang]

The original if buoyant force is gravity.
Without gravity, there is no buoyant force.
