Buoyancy and Archimedes Principle

Front

What is buoyancy?

Back

Upward force exerted by a fluid on a submerged object.

Front

Which factor does NOT affect buoyancy?

Back

Color.

Front

Who discovered the principle of buoyancy?

Back

Archimedes.

Front

Which of the following objects will float in water? (Options: Brick, concrete, steel; Rubber, paper, fabric; Metal, glass, stone; Wood, plastic, cork)

Back

Wood, plastic, cork.

Front

What does Archimedes' principle state?

Back

The buoyant force on an object is equal to the weight of the fluid displaced by the object.

Front

What is the relationship between density and buoyancy?

Back

Objects with a density less than the fluid will float; those with greater density will sink.

Front

What is the formula for calculating buoyant force?

Back

Buoyant Force = Weight of the fluid displaced.

Front

How does temperature affect buoyancy?

Back

Temperature changes can affect the density of the fluid, thus affecting buoyancy.

Front

What is the role of shape in buoyancy?

Back

Shape can influence how an object displaces fluid, affecting its buoyancy.

Front

What happens to buoyancy when an object is submerged deeper in a fluid?

Back

Buoyancy remains the same as long as the fluid density does not change.
