Buoyancy Vs Density

Buoyancy is the upward force exerted by a fluid that opposes the weight of an object submerged in it. This force arises from the pressure difference between the top and bottom surfaces of the object due to the fluid's weight. According to Archimedes' principle, an object will float if its weight is less than the buoyant force acting on it, and it will sink if its weight is greater. Buoyancy is a crucial concept in understanding how objects interact with fluids, influencing various applications from ship design to underwater exploration.

Density is defined as the mass of an object divided by its volume, typically expressed in units such as kilograms per cubic meter (kg/m³). It is a fundamental property of matter that determines how much mass is contained within a given volume. Density plays a significant role in various physical phenomena, including buoyancy, where an object's density relative to the fluid determines whether it will float or sink. Understanding density is essential in fields ranging from material science to engineering, as it influences the behavior and interaction of substances.
