Buoyant Forces and Archimedes' Principle

What does Archimedes' Principle state about the buoyant force acting on a submerged object?

• It is equal to the object's mass.

• It is equal to the weight of the displaced fluid.

• It is always greater than the object's weight.

• It is inversely proportional to the object's volume.

When an object is submerged in a fluid, how does its apparent weight change?

• It increases due to fluid pressure.

• It remains the same.

• It feels lighter.

• It feels heavier.

What is the primary reason that objects feel lighter when submerged in a fluid?

• The fluid reduces the object's mass.

• The fluid exerts an upward buoyant force on the object.

• The gravitational force on the object decreases in fluid.

• The object's density changes when submerged.

In physics, what is the collective term for substances that can flow, such as liquids and gases?

• Solids

• Plasmas

• Fluids

• Vapors

What is the upward force exerted by a fluid on a submerged object called?

• Gravitational force

• Frictional force

• Buoyant force

• Normal force

What does the term "displaced fluid" refer to in the context of Archimedes' Principle?

• The total volume of the fluid in the container.

• The fluid that moves out or up to make space for the submerged body.

• The fluid that remains in the container after submersion.

• The fluid that evaporates due to the object's temperature.

How does the buoyant force acting on an object change as more of its volume is submerged in a fluid?

• It decreases.

• It remains constant.

• It increases.

• It becomes zero.

Why can a large metal ship float on water, while a small, solid piece of the same metal sinks?

• The ship is made of a special type of metal that is lighter than water.

• The ship's hollow design allows it to displace a large volume of water, creating a large buoyant force.

• The ship's engines generate an upward thrust that keeps it afloat.

• The small metal piece is too dense to float, regardless of its shape.
