⚓ What Is Buoyant Force?
Buoyant force is the upward force exerted by a fluid that opposes the weight of an object immersed in it. Understanding buoyancy helps students explain everyday phenomena such as boats floating on water, submarines diving and surfacing, hot air balloons rising, and objects sinking or floating based on density and displacement.
This worksheet provides opportunities for students to develop a solid conceptual understanding of these important scientific principles while strengthening their observation, reasoning, and problem-solving skills.
