Here's a breakdown:
* Buoyancy is an upward force exerted by a fluid that opposes the weight of an immersed object.
* It is caused by the difference in pressure between the top and bottom of the object. The pressure is higher at the bottom because it has to support the weight of the fluid above it.
* The magnitude of the buoyant force is equal to the weight of the fluid displaced by the object, according to Archimedes' Principle.
Key points about buoyancy:
* Buoyant force always acts upwards.
* The greater the volume of fluid displaced, the greater the buoyant force.
* 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.
