Archimedes Principle

1. What is Archimedes Principle Class 9? Who stated it?

Archimedes’ principle is a property of fluids that was discovered by the ancient Greek mathematician and physicist Archimedes. It states that when an object is partially or completely submerged in a fluid i.e. liquid or gas, it experiences an upward buoyant force that is equal to the weight of the fluid that the object displaces.

2. What is Buoyancy?

Buoyancy is the phenomena due to which an object when immersed in water experiences an upward thrust. The upward force experienced by the object is called Buoyant Force.

3. How can we Experimentally Verify Archimedes’ Principle.

We can experimentally verify Archimedes Principle by immerisng an object in a liquid and observe change in the volume of the water. The detail has been discussed in the article above

4. State 2 factors on which Upthrust depends.

The two factors on which upthrust depends are: (1) The volume of the object submerged, (2)The density of the liquid in which the object is submerged.

5. When does the Object Float?

According to the statement of Archimedes’ principle, the object will float when the weight of the water is displaced equal to the weight of the object.

6. What is an Example of Archimedes’ Principle in our daily life?

One common example of Archimedes’ principle in our daily life is the experience of floating in a swimming pool or bathtub. When you get into the water, your body displaces an amount of water equal to your own volume.

8. What is Archimedes’ Principle of Density?

The Archimedes principle can also be related with density of an object to derive a ratio between the volume of the of liquid and the total volume of the solid along with the densities of the liquid and solid. When an object is placed in water and is floating: V_L ×D_L× g = V_O ×D_O ×g [W = F_B] ⇒ V_L×D_L = V_O×D_O ⇒ D_L/D_O = V_O/V_L. Thus we can conclude the ratio D_L : D_O :: V_O : V_L, for floating bodies. For sinking bodies W > F_B and D_O > D_L.

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.

In this article, we are going to learn about what is Archimedes Principle, its formula, how to derive it, its application, and its experimental verification of Archimedes
