The amount of buoyancy an item has is determined by its weight in comparison to its volume (or simply put, its density) The less dense it is, the more buoyant it is. For a full explanation of how buoyancy works go to the related question "What is the buoyancy principle?" in the Related Questions section below.

Does buoyancy work in space?
No chance of buoyancy force in free space. Buoyancy is the force is due to the weight of the expelled fluid when an object comes into that fluid. But in free space no material is present and so no expelling. Hence no buoyancy.
What branch of science is buoyancy classified under?
The phenomenon of buoyancy would be classified under the category of hydraulics.
The upward force of a liquid or air on an object that helps it float?
The force that makes things float is called buoyancy.
The contact force that acts on objects in a liquid or gas and allows objects to float is called density or buoyancy?
buoyant force
How negative buoyancy affect a blimp?
Negative buoyancy is when the gravitational pull on a diver is greater than the buoyant force. This means that the diver is being pulled downward, and that the buoyant force is doing negative work (work that is in the opposite direction of the displacement). Positive buoyancy is the opposite situation in which the buoyant force of the diver is greater than the gravitational pull, which makes the diver move upwards. Usually, a person's weight is slightly more than the weight of the displaced amount of water. For example, a person who weighs 80kg displaces 79dm2 of water, which weighs 79kg, that is, he has about 1kg of negative buoyancy. As for your question whether this negative buoancy is a unique feature for black people, the answer is no. it is related to the person's density.
Buoyancy force is determined by comparing the?
volume displaced and the specific weight of the substance
Is the bouyant force of water proportional to its depth?
No. Water is incompressible. Buoyancy is determined by density, and being incompressible the density stays the same. Once an object is submerged there's no more buoyancy to be generated.
What affect provided by water aerobics helps make the exercise beneficial?
Buoyancy
The relationship between the upward and downward forces exerted in liquids is given by the liquid's what?
A liquid's buoyancy is determined by its specific gravity (density).
What is the buoyancy of object if it has an area of 31.5 centimeters and a mass of 0.7 kilograms?
The force of buoyancy can only be determined knowing the volume (not area) of an object and the density of the fluid it is placed in. It's value is equal to the weight of the displaced fluid and is independent of the mass of the object.
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
