Buoyant force is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. In other words, it is the upward thrust of a fluid that counteracts the weight of an object submerged in it or floating on its surface.
Buoyant force is a fundamental principle in fluid mechanics and has several important applications in various fields, including physics, engineering, and naval architecture. It plays a crucial role in understanding the behavior of objects in fluids and is essential for analyzing the stability and buoyancy of ships, submarines, and other floating structures.
