Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What does Archimedes' principle state?

  • The buoyant force is less than the weight of the object
  • The buoyant force is equal to the weight of the fluid displaced
  • The buoyant force is always equal to zero

💡 Hint: Recall what happens to objects submerged in fluids.

Question 2

True or False: The center of buoyancy can change when a submerged object is tilted.

  • True
  • False

💡 Hint: Think about how the shape of an object submerged in water can shift.

Challenge Problems

Push your limits with challenges.

Question 1

A ship has a center of gravity located 3 meters above the waterline, and the metacenter is 5 meters above the waterline. Will the ship be stable or unstable?

💡 Hint: Evaluate the stability based on the vertical relationships.

Question 2

A spherical object has a diameter of 0.5 m and is submerged in water (density = 1000 kg/m³). Calculate the buoyant force acting on the object.

💡 Hint: Use the formula for the volume of a sphere and apply the force of gravity on the displaced fluid.
