Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What does Archimedes' principle state?
- A. An object will float if its density is less than the fluid's density
- B. The buoyant force is equal to weight of fluid displaced
- C. Buoyancy only applies to ships
- D. Only solid objects experience buoyancy
💡 Hint: Think of how objects behave in water.
Question 2
True or False: The center of buoyancy is the centroid of the displaced volume.
- True
- False
💡 Hint: Relate this to how shape affects buoyancy.

Question 1
A 2 m³ block of wood with a density of 600 kg/m³ is floating in water. Calculate the depth to which the block is submerged. (Density of water = 1000 kg/m³)
💡 Hint: Use the volume ratio based on densities.
Question 2
An object has a weight of 300 N when submerged in a fluid. If the buoyant force acting on it is 350 N, will the object sink, float, or be neutrally buoyant?
💡 Hint: Compare the weight to the buoyant force to assess floating vs. sinking.
