What is the principle of buoyancy?
Archimedes continued to do more experiments and came up with a buoyancy principle that a ship will float when the weight of the water it displaces equals the weight of the ship and anything will float if it is shaped to displace its own weight of water before it reaches the point where it will submerge.
What is the instrument used to measure the relative density of a liquid?
A hydrometer is an instrument used for measuring the relative density of liquids. Hydrometer consists of lead shots which makes them float vertically on the liquid. The lower the hydrometer sinks, the lesser is the density of the liquid.
What is the law of float?
Law of Floating. Whether an immersed object will float or sink, depends on the magnitudes of the actual weight W₁ of the object and the buoyant force W₂ exerted by the fluid. W₁ > W₂ : The resultant force on the object is downwards, causing it to sink. When the density of the object is greater than that of the fluid, this condition arises.
What is the Archimedes principle?
Archimedes principle formula states that a fluid exerts an upward thrust on a partially or fully immersed body, which is known as buoyant force. Due to this force, the body faces an apparent loss of weight. The apparent decrease in weight is equal to the magnitude of the buoyant force.
What is the upward thrust of a gas called?
The upward thrust is called the buoyant force.
Why do ships float in a partially submerged state?
Due to the buoyant force having greater magnitude than the ship’s weight, the ship can float in a partially submerged state. Aircraft are made using the same concept. The densities of liquids are computed using hydrometers which work according to the Archimedes principle of buoyancy.
What is the result of the weight of the fluid?
Any fluid applies equal pressure in every direction. This pressure is the result of the weight of the fluid. When an object is partially or completely submerged in a fluid, it exerts an upward force on the object. This upward force is called the buoyant force. Due to the buoyant force, there is an apparent decrease in the weight of the object.
How to tell if an object is weightless?
If the object floats on the surface , it is effectively weightless. The apparent decrease in the weight is equal to the magnitude of the upward buoyant force. The apparent weight of an object is given by the difference between the actual weight and the buoyant force.
What is the magnitude of buoyant force?
The magnitude of the buoyant force is, however, equal to the apparent decrease in the weight of the object. Therefore, Apparent decrease of the object’s weight = weight of the fluid displaced by the object.
Archimedes Principle: Definition
Archimedes Principle states that when an object is submerged in water, either partially or fully, it experiences an upward buoyant force which is equal to the weight of water displaced by the submerged object.
Apparent Weight: Explanation
The actual weight of an object when placed on any solid surface acts in the downward direction through the center of the gravity. When this object is immersed in water, it experiences an upward force which is the buoyant force.
Effects of Archimedes Principle: Floating and Sinking
When an object is immersed in water, it either floats or sinks based on the density of the object and the liquid. Let us consider W 1 as the actual weight of the object and W 2 as the buoyant force.
Things to Remember based on Archimedes Principle
Archimedes Principle discovered by Archimedes, explains the relationship between the apparent weight of an object submerged in water and the weight of the water displaced by it.

Adding chicken to a pot of boiling water ...
What is the principle of adding chicken to boiling water?
Archimedes' principle dictates that the buoyant force that acts on a body that is partially or totally immersed in a fluid is the same as the weight of the fluid that the body displaces.
Calculation of Buoyant Force
The force on the bottom of a submerged object is greater than that on its top because pressure increases with depth. Therefore, the fluid exerts a net upward buoyant force on the object . Consider a submerged cylinder as shown in figure (1)
