Answer 1

Buoyancy is the tendency of an object to float in a fluid. All liquids and gases in the presence of gravity exert an upward force known as the buoyant force on any object immersed in them. Buoyancy results from the differences in pressure acting on opposite sides of an object immersed in a static fluid. After reading this article, you will be able to explain the buoyant force and why fluids exert an upward buoyant force on submerged objects.
