The forces at work in buoyancy. Note that the object is floating because the upward force of buoyancy is equal to the downward force of gravity. In science, buoyancy ( /ËbÉÉª.Énsi, -Éntsi/ or /ËbuËjÉnsi, -jÉntsi/;) or upthrust, is an upward force exerted by a fluid that opposes the weight of an immersed object.
That is â. The upthrust on a body immersed in a fluid is equal to the weight of the fluid displaces by it. We have to derive upthrust or buoyant force to prove Archemedesâ Principle. image of upthrust. A cube A is immerged into a beaker filled with a liquid.hat is â.
