* Weight: The force of gravity pulling the object downwards.
* Buoyant Force: The upward force exerted by a fluid (liquid or gas) on an object submerged in it.
Equilibrium: When these two forces are equal and opposite, they cancel each other out. This means the object is not accelerating upwards or downwards, and therefore remains stationary in the fluid.
Example:
Think of a boat floating on water. The boat's weight pulls it downwards, but the water pushes back with an equal buoyant force. Since these forces are balanced, the boat stays afloat.
Important Note: The object doesn't necessarily have to be completely submerged for this to happen. A portion of the object can be submerged, with the rest remaining above the fluid level, as long as the buoyant force on the submerged portion is equal to the object's weight.
