Buoyancy Flashcard

Front

What direction does buoyant force act on an object immersed in a fluid?

Back

Upward on the immersed object.

Front

What shape helps keep large ships afloat?

Back

U-Shaped.

Front

If buoyancy is equal to or greater than the weight of an immersed object, the object will...

Back

Float.

Front

If an object that weighs 100 pounds is thrown in water and displaces 80 pounds of water, what will it do?

Back

It will sink.

Front

What is buoyancy?

Back

Buoyancy is the upward force exerted by a fluid that opposes the weight of an immersed object.

Front

What is the principle of Archimedes?

Back

An object submerged in a fluid experiences a buoyant force equal to the weight of the fluid it displaces.

Front

What factors affect buoyancy?

Back

The density of the fluid, the volume of the object, and the weight of the object.

Front

What is the difference between floating and sinking?

Back

Floating occurs when buoyant force equals the weight of the object; sinking occurs when the weight of the object is greater than the buoyant force.

Front

What is neutral buoyancy?

Back

Neutral buoyancy occurs when an object's weight is equal to the buoyant force, causing it to neither sink nor float.

Front

How does the shape of an object affect its buoyancy?

Back

The shape can affect how much water is displaced, influencing whether the object floats or sinks.
