Floating and Sinking

Front

What is buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid.

Front

What does Archimedes' Principle state?

Back

Archimedes' Principle states that the buoyant force on an object is equal to the weight of the fluid it displaces.

Front

How is density calculated?

Back

Density equals mass divided by volume.

Front

What condition must an object meet to float on water?

Back

An object will float on water if it is less dense than water.

Front

What does positive buoyancy mean?

Back

Positive buoyancy means that the buoyant force is stronger than the object's weight, causing it to float.

Front

What is the relationship between density and buoyancy?

Back

An object with a density less than the fluid will float, while an object with a density greater than the fluid will sink.

Front

What happens to an object with neutral buoyancy?

Back

An object with neutral buoyancy neither sinks nor floats; it remains suspended in the fluid.

Front

What is the effect of temperature on buoyancy?

Back

As temperature increases, the density of a fluid typically decreases, which can affect buoyancy.

Front

What is an example of a buoyant object?

Back

A rubber duck is an example of a buoyant object that floats on water.

Front

What is an example of a sinking object?

Back

A rock is an example of a sinking object that is denser than water.
