Here's how it works:
* Buoyancy is an upward force exerted by a fluid that opposes the weight of an immersed object.
* This force is caused by the pressure difference between the bottom and top of the object. The fluid pressure at the bottom of the object is greater than the pressure at the top, resulting in a net upward force.
* Archimedes' Principle states that the buoyant force on an object submerged in a fluid is equal to the weight of the fluid displaced by the object.
In simpler terms:
Imagine placing a block of wood in water. The water pushes up on the wood, trying to "replace" itself. If the upward buoyant force is equal to or greater than the downward force of gravity on the wood (its weight), the wood will float. If the weight of the wood is greater than the buoyant force, it will sink.
