Is Buoyancy an upward force exerted by a fluid on a body placed in the fluid?

False. It is an upward force, that (partly) counteracts the downward force of gravity for objects within a liquid. It is related to the resistance (to displacement) by the liquid molecules.

What is the force that pushes up on an object in a liquid?
That force is bouyancy. Bouyancy is also present in a gas, but its effects are usually negligible except on objects with very low densities.
What is the pressure exerted by a fluid is the total force exerted by the fluid divide by?

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.
Why do you feel 'lighter' in water than in air?
Water is denser than air, and thus has a buoyancy effect that supports your weight more. You feel lighter because you are lighter. A scale under you would reflect the difference. Bear in mind, there is a difference between "weight" and "mass". Your mass would still be the same.
How does buoyancy affect the mass of an object?
If the average density of an object is less than water (1.0 g per mL) it will float in water, and if it is more than 1.0g/mL it will sink in water. So the lower the density, the greater the buoyancy.
What is a upward force exerted on objects in a fluid?
The upward force exerted on an object in a fluid is buoyancy.
What force is the upward force exerted on any object in a fluid?
The upward force exerted on an object in a fluid is buoyancy.
An upward force exerted by a fluid on a submerged object?
buoyancy
What makes poo sink or float?
Buoyancy, which is an upward acting force exerted by a fluid , that opposes an object's weight.
What is the scientific definition of a buoyant force?
Buoyancy is an upward thrust or force exerted by a fluid , that opposes an object's weight.
What is buoyancy force?
Buoyancy is an upward acting force. It is caused by fluid preassure which opposes an objects weight ( their gravitational pull downwards ).
Buoyancy is an upward force exerted by a fluid on a body placed in the fluid.?
Yes, and the strength of the force is equal to the weight of the fluid displaced by the body.True
What is the force exerted on an object is equal to the weight of the fluid displaced?
buoyancy is the upward force that keeps things afloat. The net upward buoyancy force is equal to the magnitude of the weight of fluid displaced by the body. This force enables the object to float or at least seem lighter
What is buoyancy.?
Buoyancy is an upward acting force. It is caused by fluid preassure which opposes an objects weight ( their gravitational pull downwards ).
IN what direction does a liquid exert force?
if you are asking in which direction does a liquid exert pressure on the object? then, liquid exert force in the upward direction which is called buoyancy. Brief description: when a body is partially or wholly immersed, it displaces the fluid. the displaced fluid had tendency to regain it's original position position. due to this, an upward force is exerted on the body by the displaced fluid. this upward force actiong on the the body immersed in a fluid is called upward thrust or buoyancy force or simply buoyancy.
