Buoyancy and Archimedes Principle

Front

What is buoyancy?

Back

Buoyancy is the upward force exerted by a fluid on an object that is submerged or floating in it.

Front

What is Archimedes' Principle?

Back

Archimedes' Principle states that an object submerged in a fluid experiences a buoyant force equal to the weight of the fluid displaced by the object.

Front

When an object is fully submerged in a fluid, the buoyant force is equal to what?

Back

The weight of the fluid displaced by the object.

Front

What is the formula to calculate buoyant force?

Back

Buoyant force = Weight of the fluid displaced.

Front

What is the unit of density?

Back

g/cm^3, lbs/in^3, or kg/m^3.

Front

Which of the following objects will float in water? Wood, plastic, cork or Brick, concrete, steel?

Back

Wood, plastic, cork.

Front

Which factor does NOT affect buoyancy?

Back

Color.

Front

What is the relationship between density and buoyancy?

Back

An object will float if its density is less than the density of the fluid it is in.

Front

How does temperature affect buoyancy?

Back

Temperature can affect the density of the fluid, which in turn can affect buoyancy.

Front

What happens to the buoyant force if an object is partially submerged?

Back

The buoyant force is still equal to the weight of the fluid displaced by the submerged part of the object.
