Yes they are different things. Buoyant force is always upward. Weight is always downward.
Also ...
-- Weight depends on the object's mass.
-- Buoyant force depends on its volume, and on what it's floating in.
True. The buoyant force acting on an object immersed in a fluid is equal to the weight of the fluid that the object displaces. Therefore, by knowing the weight of the object, you can determine the buoyant force on it.
True. According to Archimedes' principle, an object placed in a fluid will experience a buoyant force equal to the weight of the fluid it displaces. If this buoyant force is equal to the weight of the object, the object will float.
Actually, it's Archimedes' principle that states that the buoyant force on an object is equal to the weight of the fluid it displaces. This principle helps explain why objects float or sink in fluids like water.
If the buoyant force is less than the weight, the object must accelerate down. If it ever displaces enough water to increase the buoyant force to equal its weight, then it'll stop sinking. Otherwise, it goes straight to the bottom.
Newton's principle of buoyancy states that the buoyant force acting on an object immersed in a fluid is equal to the weight of the fluid displaced by that object. This principle helps explain why objects float or sink in fluids based on their density relative to the fluid.

True. According to Archimedes' principle, an object placed in a fluid will experience a buoyant force equal to the weight of the fluid it displaces. If this buoyant force is equal to the weight of the object, the object will float.
No. The buoyant force on an object is the portion of its weight that appears to vanish when the object is in any fluid (could be either a liquid or a gas). If the object happens to float in a particular fluid, then the buoyant force at that moment is equal to the object's weight. Notice that the buoyant force on an object will be different in different fluids.
False, this is Archimedes's Principle.

FALSE
True. The pressure at the bottom of a submerged object is greater than the pressure at the top due to the weight of the fluid above it. This pressure difference creates an upward buoyant force that helps support the object in the fluid.
FALSE
False. Objects sink in water when the buoyant force acting on them is less than the weight of the object. This can happen if the object is denser than water or if it is not shaped in a way to displace enough water to counteract its weight.
