When sun light wars the air on the ground its density reduces as with your object under water you have no upward (pressure-)force because there is nothing beneath the war air bubble with a higher density. The buoyancy force, $F_\mathrm$ in this case should be called buoyancy needs to be discussed.Ī very similar effect are thermals. (The reader has to decide whether a body on the ground is still immersed.) In physics, buoyancy or upthrust, is an upward force exerted by a fluid that opposes the weight of an immersed object. This article also gives the defintion of buoyancy as: The articel on buoyancy over at Wikipedia explains very good how the following equations are set-up.
