What causes Buoyant Force?
An object when immersed in a liquid experiences buoyant force. This force is upward in the direction opposite to the gravitational force, this is responsible for the reduced weight of the object inside the fluid. It’s known that the pressure increases with the depth of the fluid. The pressure at the bottom of the object is greater than the pressure experienced at the top, this difference creates the net force experienced by the object inside the liquid, which is called buoyant force.
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. Let’s learn the buoyancy definition, buoyancy equation, and its examples in detail.
