Question 1
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.
💡 Hint: Think of the force acting on submerged objects.
Question 2

Challenge Problems
Push your limits with challenges.
Question 1
Calculate the buoyant force on a 10 kg object submerged in water (density = 1000 kg/m³).
💡 Hint: Use the formula for buoyancy: Buoyant force = density * volume * g.
Question 2
An object has a center of gravity below its metacenter. Discuss the implications for its stability in water.
💡 Hint: Think about how the forces interact when disturbed.
