Buoyancy occurs in fluids, which are gases and liquids. Hot air balloons are buoyant in air and ships are buoyant in water for examples.
When the buoyancy of objects exceeds the weight of those objects, the objects rise. When the weight exceeds the buoyancy they sink. And when the buoyancy equals the weight of the objects they float.

∙ 15y agoBuoyancy is often described as displacing water, but the critical part is that the displaced water has to go somewhere, and the only somewhere for it to go is upwards (since water is incompressible). Thus a 100 ton ship lifts 100 tons of water upward (spread across the entire ocean ... but that makes no difference). The 100 tons of water pushing down lifts up the ship : buoyancy.

Was buoyancy always called buoyancy?
yes, it is the same.
Could you find a scientific sentence with the word buoyancy?
We are merely testing the buoyancy of several types of ping pong balls.
How do you use buoyancy?
Buoyancy is what keeps a boat floating on the top of the water. Buoyancy is what makes a helium balloon float in the air.
What is zero percent buoyancy?
Zero percent buoyancy is actually just sinking. Something that sunk is having zero percent buoyancy
What are facts about buoyancy?
buoyancy has to deal with density, gravity, air, and water
Does increase pressure in a tank increase its buoyancy?
no, it will not, in a compressible gas, the contents will increase in density, thus reducing its buoyancy. in an incompressible liquid or solid, no noticeable change will occur.
What affect provided by water aerobics helps make the exercise beneficial?
Buoyancy
What kind of buoyancy do submarines have when they are resting on the surfce of the ocean?
Positive Buoyancy. When submarine submerges, it initially uses negative buoyancy to submerge, and then levels out to neutral buoyancy.
What does buoyancy help with?
High buoyancy=easy to float
Does freshwater have buoyancy?
Yes, all fluids have buoyancy.
Was buoyancy always called buoyancy?
yes, it is the same.
Could you find a scientific sentence with the word buoyancy?
We are merely testing the buoyancy of several types of ping pong balls.
When was buoyancy found?
The phenomena of buoyancy was first discovered by Archimedes.
How can buoyancy be demonstrated?
buoyancy can be demonstrated if you float something because buoyancy is when something floats for example a boat floating in water
How do you use buoyancy?
Buoyancy is what keeps a boat floating on the top of the water. Buoyancy is what makes a helium balloon float in the air.
What is zero percent buoyancy?
Zero percent buoyancy is actually just sinking. Something that sunk is having zero percent buoyancy
How does salt reduce buoyancy in water?
Salt actually increases buoyancy.
