Here's why:
* Buoyant force is the upward force exerted by a fluid (like water or air) on an object submerged in it. This force is equal to the weight of the fluid displaced by the object.
* Weight is the force of gravity acting on an object's mass.
When the object's weight is greater than the buoyant force, the downward force of gravity is stronger than the upward force of buoyancy. This results in a net downward force, causing the object to sink.
Example: A rock is denser than water, so its weight is greater than the buoyant force acting on it. This is why rocks sink in water.
