Fluid Pressure and Gravity

Force divided by the area it is applied over is

• mass

• density

• pressure

• volume

Compared to a man standing on a tall mountain, a man standing at sea level 

• has less atmospheric pressure on him 
• has more atmospheric pressure on him 
• weighs less 
• has more mass 

When you squeeze a bottle in the middle with a force what force is applied to the fluid at the top of the bottle 

• less force 
• more force 
• the same force
• cannot be predicted 

What system used in many applications like forklifts or jacks works on Pascal's principle 

• hydraulics 
• sprockets 
• widgets
• brakes 

whose principle says when a fluid's speed increases the pressure of that fluid decreases 

• Archimedes'
• Pascal's
• Einstein's
• Bernoulli's 

What force causes the wood to float 

• weight
• density
• buoyant
• gravity

whose principle says buoyant force = the weight of the fluid an object displaces 

• Archimedes
• Pascal
• Bernoulli
• Einstein 

If you place an object in a fluid and it sinks which is true 

• its weight is less than the buoyant force
• the fluid is more dense than the object
• its weight  is greater than the buoyant force
• dead men tell no tales 

When a planes' wing moves through air the air over the top moves faster creating a force called 

• drag
• weight displacement
• torque
• lift 

The ratio of an objects mass to its volume is its 

• density
• pressure
• buoyancy 
• height
