Question 1.
What is buoyancy?
Show hintHide hint
Think about the forces acting on an object submerged in water.
Question 2.
Define center of buoyancy.
Show hintHide hint
Consider where the buoyant force acts.
3Question 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.
Show hintHide hint
Think about how objects behave in water.
4Question 4.

- True
- False
Show hintHide hint
Consider scenarios with different shapes.
Question 5.
