11.4.1. Archimedes' Principle

Try these first

1. 1.

   What is buoyancy?

   Hint

   Think about the forces acting on an object submerged in water.

2. 2.

   Define center of buoyancy.

   Hint

   Consider where the buoyant force acts.

3. 3.

   What does Archimedes' Principle state?

   • A body submerged in a fluid experiences an upward buoyant force equal to its weight.
   • All objects sink in a fluid.
   • Fluids exert no forces on objects.

   Hint

   Think about how objects behave in water.

4. 4.

   True or False: The center of buoyancy is always the same as the center of gravity.

   • True
   • False

   Hint

   Consider scenarios with different shapes.

5. 5.

   A cylindrical object with a radius of 0.5 m and a height of 2 m is submerged in water. Calculate the buoyant force acting on this object.

   Hint

   Calculate the volume of the cylinder first.

6. 6.

   Design a floating object to ensure maximum stability. Explain the considerations regarding center of gravity and buoyant force.

   Hint

   Focus on the relationship between the center of buoyancy and center of gravity.
