Title: Gravity's Effect on Buoyant Force
Post by: Sleepy_Sentry on October 13, 2004, 03:50:26 am
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!)

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?

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..  ???

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