BUOYANCY. When an object is immersed partially or fully in a liquid, it experiences an upward force. Thisupward force is known as buoyantforce and this phenomenon is known as buoyancy. Buoyancy is also known as up thrust.The force of buoyancy is given as,F = Vρgwhere V is the volume of the liquiddisplaced, ρ is the density of liquid and g is acceleration due to gravity.Buoyancy helps ships and boats to float on water, helium balloons in air etc. ARCHIMEDE PRINCIPLE Archimedes principle states that when a body is immersed wholly or partially in a liquid, it experiencesan upward buoyant force of magnitude equal to the weight of the liquid displaced by it. Buoyant force = Weight of displaced liquid Weight of displaced liquid = Mass of the displaced liquid × Acceleration due to gravity= Density of the liquid × Volume of the displaced liquid × Acceleration due to gravity ∴Volume of the displaced liquid = Volume of the object that is immersed in the liquid ∴Weight of the displaced liquid = Volume of the object immersed in the liquid × Density of the liquid × Acceleration due to gravityHence, we can write the magnitude of the upthrust on an object that is immersed in a liquid as Buoyant force = Volume of the object × Density of the liquid × Acceleration due to gravity Since buoyant force depends on the density of the liquid in which it is immersed, it is different in different liquids for the same object.

The tendency of a fluid to exert an upward force on an object immersed in it is called buoyancy.
Archimedes' principle is the apparent loss in weight of the liquid displaced by the immersed part of the body.
