WHO stated that the buoyant force on an object in a fluid is an upward force equal to the weight of the volume of fluid that the object displaces?
Archimedes’ principle
Archimedes’ principle, physical law of buoyancy, discovered by the ancient Greek mathematician and inventor Archimedes, stating that any body completely or partially submerged in a fluid (gas or liquid) at rest is acted upon by an upward, or buoyant, force, the magnitude of which is equal to the weight of the fluid …
What force pushes up on an object in the fluid?
the buoyant force
When an object is placed in a fluid, the fluid exerts an upward force we call the buoyant force. The buoyant force comes from the pressure exerted on the object by the fluid.
What is the upward force in a liquid quizlet?
Water and other fluids exert an upward force called the buoyant force that acts on a submerged object.
When an object floats in a liquid The buoyant force is the weight of an object quizlet?
Terms in this set (16) The ability of a fluid to exert an upward force on an object placed in/on it. The upward force that acts opposite of the direction of gravity. The buoyant force of an object is equal to the weight of the fluid displaced by the object.
In what direction does the buoyant force on an object immersed in a liquid?
The answer is: Buoyant force acts in the upward direction on an object immersed in a liquid.

Is a measure of the upward force a fluid exerts on an object that is submerged?
buoyant force is the upward force a fluid exerts on an object. Archimedes’ Principle is the fact that buoyant force is equal to the weight of the displaced fluid.
What is the force that acts in an upward direction against the force of gravity?
Buoyant force acts in the upward direction, against the force of gravity so it makes an object feel lighter.
When an object floats in a liquid The buoyant force is?
An object will float if the buoyancy force exerted on it by the fluid balances its weight, i.e. if FB=mg F B = mg . But the Archimedes principle states that the buoyant force is the weight of the fluid displaced. So, for a floating object on a liquid, the weight of the displaced liquid is the weight of the object.
Why is buoyant force always upwards?
The buoyancy force is caused by the pressure exerted by the fluid in which an object is immersed. The buoyancy force always points upwards because the pressure of a fluid increases with depth.
In what direction does the force on an object?
The force of friction always acts on all the moving objects and its direction is always opposite to the direction of motion.
What happens to an object when it is immersed in a liquid?
When an object is immersed in a liquid it experiences an upward force known as Buoyant Force. This phenomenon of experiencing an upward force is known as Buoyancy. It is as an upward force exerted by a fluid that opposes the weight of an object immersed in a fluid.
As discussed, the buoyant force is the upward force exerted on an object that is wholly or partly immersed in a fluid. This upward force is also called as Upthrust. It is due to the buoyant force that a body submerged partially or wholly in a fluid appears to lose its weight i.e. appears to be lighter.
Where does the term buoyant force come from?
The term buoyant force refers to the upward-directed force that a fluid exerts on an object that is partially or completely immersed in the fluid. The buoyant force arises from differences in hydrostatic pressure – the pressure exerted by a static fluid.
Which is an example of a force in a fluid?
You can think of two examples a jet and a glider. Fluids exert a force that opposes the motion of objects moving through fluids, this force is called drag. Drag is usually caused by an irregular flow of air, an irregular or unpredictable flow of fluids is known as turbulence.
