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.

What happens to the wood ball when it is submerged in water?

• It accelerates downward.

• It moves horizontally.

• It remains at rest.

• It accelerates upward.

Why does the wood ball accelerate upward in water?

• It has no density.

• Its density is less than water.

• Its density is greater than water.

• It is heavier than water.

What is the behavior of the rubber ball when submerged in water?

• It accelerates upward.

• It remains at rest.

• It accelerates downward.

• It moves in a circular motion.

Why does the rubber ball accelerate downward in water?

• Its density is equal to water.

• Its density is less than water.

• It has no density.

• Its density is more than water.

What happens to the water balloon when submerged in water?

• It accelerates upward.

• It accelerates downward.

• It moves in a spiral.

• It remains at rest.
