Why does an Object float or sink in the water?
Any liquid can be considered a concoction of many overlying layers. These layers are lying one over another and have fluctuating pressure. Since the pressure increases with depth, thus the pressure at the bottom will be more than the pressure at the top which will cause the buoyant force. The difference in pressure at these layers gives rise to the buoyant force. The magnitude of the force is given by the weight of the liquid displaced by the object submerged in the liquid. Due to this phenomenon, objects float in the water.
Buoyant Force
Buoyancy is a phenomenon due to the buoyant force that causes an object to float. When you put an object in a liquid, an upward force is exerted on the object by the liquid. This force is equal to the weight of the liquid that has been displaced. The amount of liquid that has been displaced depends upon the density and the volume of the object immersed in the liquid. Have you ever wondered why an iron nail sinks in water, but a ship made up of iron floats? And why does an iron ball sink but a plastic ball of the same size floats in water? These wonders happen due to the phenomenon known as Buoyancy. Letâs learn the buoyancy definition, buoyancy equation, and its examples in detail.
