Buoyant Force Demonstrated: Three Objects in Water

The video explains the behavior of three objects submerged in water: a wood ball, a rubber ball, and a water balloon. The wood ball accelerates upward due to its lower density compared to water, resulting in a greater buoyant force than gravitational force. The rubber ball, being denser than water, experiences a stronger gravitational force than buoyant force, causing it to accelerate downward. The water balloon remains at rest because its density matches that of water, balancing the buoyant and gravitational forces.

How does the density of an object affect its buoyant force in water?

What is the relationship between buoyant force and gravitational force for the water balloon?
