Welcome back, explorers of the fluid world! Today, we're plunging into the intriguing concept of buoyant force and Archimedes' Principle. We'll delve into everyday examples, understand key formulas, and solve some engaging questions.
What is Buoyant Force?
What is Buoyant Force?
Buoyant force is the upward force exerted by a fluid on an object placed in it. This force is what makes objects float or sink depending on their density relative to the fluid.
Archimedes' Principle
Archimedes' Principle
Archimedes' Principle states that the buoyant force on an object immersed in a fluid is equal to the weight of the fluid displaced by the object.
Everyday Examples
Everyday Examples
Ships and Boats: Ships float because they displace a large volume of water, creating a buoyant force equal to the weight of the ship.
Hot Air Balloons: The buoyant force from the less dense hot air inside the balloon allows it to rise and float in the cooler, denser air outside.
Icebergs: Icebergs float in the ocean because the density of ice is less than that of seawater, allowing part of the iceberg to stay above the water surface
