Buoyant Force

An object will _______ if the weight of it is equal to the weight of the water in which it is in. 

• Float
• Sink
• Expand
• Shrink

A buoyant force is an upward force applied on an object by a 

• Substance
• Fluid
• Pressure
• Displacement

An object will ______ if its' density is greater than the density of the fluid it is in. 

• Expand
• Shrink
• Float
• Sink

Pressure=

• force/volume

• volume/area

• mass/volume

• force/area

An object weighs 500 N. It displaces 150 N of water. While in water, the object's weight is

• 500N

• 650N

• 250N

• 350N

To float in water, an object must

• be less dense than water

• be more dense than water

• have less surface area than water

• have more surface area than water

Joseph weighs 290N and displaces 300N of water as he swims under water in a pool. What is the buoyant force on Joseph?

• 10 N upward

• 300 N upward

• 290 N downward

• 590 N downward

Which object, if thrown into a liquid, will have a greater buoyant force?

• Balloon
• Apple
• Rock
• Cell Phone

How does Archimedes principle relate to Pascal's principle in fluid mechanics?

• They are completely unrelated principles

• Archimedes principle only applies to solids, not fluids

• Both principles are fundamental in fluid mechanics and are used to understand the behavior of fluids under different conditions.

• Pascal's principle is used for understanding the behavior of gases, not fluids

Which liquid is the least dense?

• oil
• water
• syrup 
• plastic bottle
