Buoyancy

Buoyancy is the ability of an object to float in a fluid, such as water or air. It is a result of the upward force exerted by the fluid on the object.

Principle of Buoyancy

The principle of buoyancy is based on Archimedes' principle, which states that the buoyant force acting on an object submerged in a fluid is equal to the weight of the fluid displaced by the object.

Factors Affecting Buoyancy

• Volume: The greater the volume of an object, the greater the buoyant force acting on it.
• Density: An object with a lower density than the fluid will float, while an object with a higher density will sink.
• Fluid Density: The denser the fluid, the greater the buoyant force acting on the object.

Applications of Buoyancy

Buoyancy has various practical applications, including the design of ships, submarines, hot air balloons, and life jackets.
