Here's a breakdown:
* Buoyant Force: This is the upward force exerted by a fluid (liquid or gas) on an object that is partially or fully immersed in it.
* Weight of Displaced Fluid: When an object is submerged in a fluid, it pushes some of the fluid out of the way. The weight of this displaced fluid is equal to the buoyant force acting on the object.
In simpler terms:
Imagine placing a block of wood in a bathtub full of water. The wood sinks until it displaces enough water to equal the weight of the wood itself. The water pushing back upwards on the wood (buoyant force) is exactly the same as the weight of the water the wood pushed out of the way.
Important points to remember:
* If the buoyant force is greater than the weight of the object, the object will float.
* If the buoyant force is less than the weight of the object, the object will sink.
* If the buoyant force is equal to the weight of the object, the object will be suspended in the fluid.
