When an object is completely or partially immersed in a fluid, its weight reduction is appreciated. This virtual decrease in weight is equal to the weight of the fluid removed by the object. The property of a fluid that causes it to exert a force on the object is called uplift or buoyant force. This force acts on the center of gravity of the fluid removed by objects, which is called the center of buoyancy. The center of gravity of the fluid displaced by the floating object is called the buoyancy center. Let's take an awesome quiz about Buoyant Force Buoyancy or Upthrust.
