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
False, this is Archimedes's Principle.
because bouyant force is the result of the displacement of the fluid an object is in, if a fluis is displaced by the volume of an object the weight of the fluid being displaced is pushing up on the object
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.
FALSE
FALSE
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.

true
A buoyant force is produced when an object is completely or partially submerged in a fluid at rest .
False It should read: The amount of matter in an object is its mass (not weight)
