 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. Title: topic113 Post by: Fu-Kwun Hwang on October 14, 2004, 06:55:25 am 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!)

Title: topic113 Post by: auriliea on November 04, 2005, 10:19:28 am 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? Title: topic113 Post by: Fu-Kwun Hwang on November 04, 2005, 04:46:57 pm 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.

Title: Re: Gravity's Effect on Buoyant Force Post by: Fu-Kwun Hwang on January 10, 2012, 08:19:15 pm The original if buoyant force is gravity.Without gravity, there is no buoyant force.
