Archimedes' Law of Floatation Explained

Students with an affinity for Physics always have a quest for gaining knowledge about the mysteries of this world. Have you wondered how a vast ship sails calmly on the sea? Or, how a hot air balloon happens to go up in the air? Unfortunately, students cannot get all their questions answered in a classroom setting as there are several studentr seeking the attention of teachers. In such a case, you must consider hiring a private Physics tutor who will not only clear all your doubts but also explain the concepts further with the help of illustrations. In this article, we will discuss about the Archimedes law of floatation wherein the lies the answer to the above questions.

It is known that Archimedes was one of the best mathematicians of his time. He was also a physicist and an inventor. He was Greek by birth and there are several amazing inventions to his credit. He is known for the famous principle of floatation and the screw propeller. His works in the field of math includes discovering infinitesimals, formulas for measuring a circle, spheres, parabolas, cylinders and cones. The principle of floatation remains of his most recognized and popular inventions till date.

You will find it fascinating to know that Archimedes devised with most of his inventions to help his nation during the time of war. However, this principle was invented when a king asked him to verify the purity of a golden crown without harming it in any way. After days of pondering over it, the great scientist came up with an amazing solution and he took to the streets shouting 'eureka, eureka' in joy. The answer that he found was that he can find the density of the crown by measuring the volume of water that the crown displaced when immersed in a tub.

Thus, the Archimedes' law of floatation states that an object, whether wholly or partially submerged in liquid, experiences an upward thrust and the force is equal to the volume of the liquid displaced by the object. It is interesting to note that for any object that is completely submerged in liquid, the amount of fluid displaced is equal to its volume. And for an object that floats on a liquid surface, the volume of the displaced fluid is same as that of the object. This object experiences an upward force known as the buoyant force.
