Buoyant IG

An object will NOT sink if its weight is ______ the buoyant force.

• Less than or equal to

• Greater than or equal to

• Similar to and almost equal

• Different from and almost equal

_______ pushes an ice cube to the top of a glass of water.

• Buoyant force

• A sinking object

• Density

• Compressed air

Buoyancy is the tendency for objects to float in a fluid. We consider buoyancy the _____

• gravitational pull

• downward pull on an object

• Anti-gravity force

• normal force

If an object sinks in a fluid, _____.

• the density of the fluid is greater than the density of the object

• the density of the fluid is less than the density of the object

• the density of the fluid is equal to the density of the object

• density has nothing to do with whether an object sinks or floats, only which state of matter the object is

An object will be partially submerged in a fluid if __.

• the weight of an object is greater than the buoyant force

• the weight of an object is less than the buoyant force

• the weight of an object is equal to the buoyant force

• he weight doesn't affect if an object sinks, only its state of matter

A ball floats, submerged halfway, in a liquid. Which of the statement is true?

• Ball’s weight is equal to the weight of the fluid displaced

• Ball’s density is the same as the liquid’s density

• Buoyant force on the ball is less than the weight of the ball

• Buoyant force on the ball is greater than the weight of the ball

Which of the following statements is the condition for an object to float?

• Weight of the object is equal to the weight of the displaced liquid

• Weight of the object is greater than the buoyant force

• Volume of the object is equal to the volume of the displaced fluid

• Volume of the object is greater than the volume of the displaced fluid

Which of the following statements is not correct regarding the Buoyant force?

• It is always equal to the weight of the object

• It depends on the weight of the displaced fluid

• It is equal to the downward force on a partially submerged object

• It is equal to difference between real and apparent weight of a submerged object

The buoyant force on an object does NOT depend on the________________.

• volume of the object

• free-fall acceleration

• depth of the submerged object

• volume of the displaced liquid

Which of the following statements is correct according to Archimedes’ principle?

• The buoyant force depends on the weight of the object only

• The buoyant force is equal to the net force on a submerged object

• The buoyant force depends on the weight of the displaced fluid only

• The upward force is equal to the net force on a partially submerged object
