Archimedes principle

Archimedes' principle states that a body immersed in a fluid experiences an upward force equal to the weight of the fluid displaced, which explains why objects float or sink. The buoyant force acting on an object is determined by the volume of fluid displaced and the fluid's density. This principle is applied in designing ships, submarines, and instruments like lactometers and hydrometers.

Archimedes principle and Buoyancy By:- Aafreen Mairaj 9E
Archimedes principle – The Law  Archimedes’ Principle Archimedes Principle states that when a body is immersed partially or fully in a fluid, it experiences an upward force that is equal to the weight of the fluid displaced by it. The principle is most frequently applied to the behavior of objects in water, and helps to explain floating and sinking, and why objects seem lighter in water. It also applies to balloons in the air.
Buoyant force or up thrust When a body is immersed partially or completely inside a fluid it experiences an upward force called the Buoyant Force The Buoyant force acting on an object depends upon two factors: i. The volume of the body immersed i.e. volume of the fluid displaced . ii. Density of the fluid.
Buoyant force = weight => the object floats Buoyant force > weight => the object moves up Buoyant force < weight => the object moves down Buoyant force and flotation
Application on Archimedes Principle Used in designing ships and submarines. Used in making Lactometers, which are used to determine the purity of a sample of milk . Used in making Hydrometers , which are used for determining density of liquids.
