hey can anyone please tell me what is upthrust

Question

Answer

In physics, buoyancy or upthrust, is an upward force exerted by a fluid that opposes the weight of an immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus the pressure at the bottom of a column of fluid is greater than at the top of the column.

Answer

Up thrust =buoyant force

Answer

Upthrust is force exerted by water on the object that is immersed in a fluid. The force is also called buoyant force and is equal to the amount of water displayed by the object.

Answer

The upward force is exerted by the water on heavy object in an  particular direction is known is upthrust or beyont force .

Answer

The perpendicular force act on any body is called upthurst

Answer

Upthrust

Upthrust, also known as buoyant force or buoyancy, is a phenomenon in physics that occurs when an object is submerged in a fluid. It is the upward force exerted by the fluid on the object, opposing the force of gravity acting on the object. This force is responsible for the apparent loss of weight experienced by objects when submerged in a fluid like water.

Principle of Archimedes

The principle of Archimedes, formulated by the ancient Greek mathematician Archimedes, is the fundamental principle behind upthrust. According to this principle, any object submerged in a fluid experiences an upward force equal to the weight of the fluid displaced by the object. This principle helps explain why some objects float while others sink.

Factors Affecting Upthrust

Several factors influence the magnitude of upthrust experienced by an object submerged in a fluid:

1. Density of the Fluid: The density of the fluid plays a crucial role in determining the upthrust. If the fluid's density is greater than the object's density, the object will float. Conversely, if the object's density is greater than the fluid's density, it will sink.

2. Volume of the Object: The volume of the object directly affects the upthrust. Larger objects displace more fluid and experience a greater upthrust.

3. Gravity: The force of gravity acting on the object also affects the upthrust. A higher gravitational force would increase the object's weight and reduce the effect of upthrust.

Applications of Upthrust

Upthrust has several practical applications in our daily lives and various fields:

1. Ship and Boat Design: Understanding upthrust is vital in designing ships and boats to ensure they float and remain stable in water.

2. Hot Air Balloons: Hot air balloons utilize upthrust to remain airborne. By heating the air inside the balloon, it becomes less dense than the surrounding air, resulting in an upward buoyant force.

3. Swimming and Diving: Upthrust helps swimmers and divers float in water, making it easier for them to move and stay afloat.

4. Hydrodynamics: Upthrust plays a crucial role in studying the behavior of fluids and their interaction with objects, leading to advancements in various fields such as engineering, architecture, and environmental studies.

In conclusion, upthrust is the upward force exerted by a fluid on an object submerged in it. The principle of Archimedes explains this phenomenon, and factors such as fluid density, object volume, and gravity influence the magnitude of upthrust. Understanding upthrust has practical applications in various fields and helps us comprehend the behavior of fluids.

Answer

upthrust =buoyant force..So when an object is fully or partially immersed, the fluid exerts an upward force called buoyant force..it is called upthrust because its an force acting upwards in a perpendicular direction..

Answer

upthrust is also known as a buoyant force

Answer

Upthrust force is a force which is exert by a liquid on the object impressed on it is called upthrust or buoyant force.

Answer

Upthrust – this is all to do with objects immersed in fluids, either partially (some of the object sticks out of the fluid) or totally (all the object is below the fluid).
A fluid can actually be a liquid or a gas but to make life easy we will stick to a liquid – say water. We all know what that is!
Upthrust is defined as the upward force on the object provided by the liquid because the object has 'displaced' some of the fluid. The volume below the water level that is now occupied by the object used to be filled with water and if the object has a different density than water there will be an upward force on the object. If this force is less than the weight of the object the object will sink.
If you lift a heavy stone by a rope and then dangle it in water you will find it appears to weigh less, this is because of the upthrust pf the water on the rock. It is much easier to lift things in a swimming pool – the upthrust of the water helps support them.
If something floats the upthrust is equal to the weight of the object.
Archimedes explained this by his principle:When a body is wholly or partially immersed in a liquid there is an upthrust which is equal to the weight of liquid displaced.
