Question 1.
Define buoyancy.
Show hintHide hint
Think about why objects float.
Question 2.
What is Archimedes' principle?
Show hintHide hint
Consider the relation between an object's weight and the fluid it pushes away.
3Question 3.
What does Archimedes' principle state?
- An object sinks if it's heavier than the fluid.
- The buoyant force is equal to the weight of the fluid displaced.
- All objects float in water.
Show hintHide hint
Think of the force acting on submerged objects.
4Question 4.
Is buoyancy a downward force?
- True
- False
Show hintHide hint
Remember how it allows things to float.
Question 5.
Calculate the buoyant force on a 10 kg object submerged in water (density = 1000 kg/m³).
Show hintHide hint
Use the formula for buoyancy: Buoyant force = density * volume * g.
Question 6.
An object has a center of gravity below its metacenter. Discuss the implications for its stability in water.
Show hintHide hint
Think about how the forces interact when disturbed.
