* Buoyant Force: This is the upward force exerted by a fluid (like water or air) on an object submerged in it. It's directly related to the volume of fluid displaced by the object.
* Weight: This is the downward force due to gravity acting on the object's mass.
When the buoyant force is greater than the weight, the upward force pushing the object up is stronger than the downward force pulling it down. This creates a net upward force, causing the object to rise and float.
Example: Think of a boat. It's made of materials denser than water, meaning it would sink if just dropped in. But the boat's shape is designed to displace a large volume of water, creating a buoyant force larger than its weight, allowing it to float.
