Buoyancy

Buoyancy

Buoyancy, or upthrust, is the force exerted by a fluid opposing the weight of a partially or fully immersed object. The pressure of a fluid increases with depth below the fluid's surface because of the weight of the fluid above. Thus, the pressure at the bottom of a container of fluid is greater than at the top of the container. Similarly, the pressure at the bottom of an object submerged in a fluid is greater than at the top of the object. This pressure difference results in a net upward force on the object. The magnitude of the force is proportional to the pressure difference, and, as explained by Archimedes' principle, is equivalent to the weight of the fluid that would otherwise occupy the submerged volume of the object, i.e. the displaced fluid.

Buoyancy (film)

Buoyancy is a 2019 Australian drama film directed by Rodd Rathjen. It was selected as the Australian entry for the Best International Feature Film at the 92nd Academy Awards, but it was not nominated.
