What is Archimedes’ Principle?
Archimedes Principle states that when an object is submerged in a fluid, it experiences an upward buoyant force equal to the weight of the fluid it displaces. This principle explains why objects appear to weigh less when placed in a fluid and why some objects float while others sink. The buoyant force is directly proportional to the volume of the fluid displaced by the submerged object, and it counteracts the object’s weight. As a result, if the weight of the fluid displaced is greater than or equal to the weight of the object, it will float, while if the weight of the fluid displaced is less, the object will sink.
It was in the year 246 BC that Archimedes had an idea about the weight displacement by liquids. After a lot of tests about the density and volume of different things, he stated the “Archimedes’ Principle”.
Archimedes’ Principle Definition
“Any object, totally or partially immersed in a fluid or liquid, is buoyed up by a force equal to the weight of the fluid displaced by the object.” – Archimedes
It means that when a body is partially or completely submerged in a liquid, it experiences an apparent loss in because of a force acting in upward direction (Buoyancy), which is equal to the weight of liquid displaced by the submerged part of the body. This force acting in upward direction was later named as Upthrust or force acting vertically upwards.
Archimedes Principle Example
The best example of Archimedes Principle is that when a ship is launched into water it displaces the amount of water equal to its weight.
Archimedes Principle
Archimedes Principle is a fundamental concept in fluid mechanics, credited to the ancient Greek mathematician and physicist Archimedes. According to Archimedes’ Principle, when an object is immersed in a fluid the object experiences an upward force whose magnitude is equal to the weight of the fluid displaced by the object.
Archimedes’ principle has applications in various fields, from ship design to understanding the behavior of objects in water. Archimedes’ Principle is important for class 9 students.
