Fluids & Pressure

The amount of force pushing on an area is the definition of....

• Fluid
• Viscosity
• Barometer
• Pressure

A force is applied in a closed container, the pressure increases the same amount. EX: squeezing a water bottle or toothpaste

• Archimede's Principle
• Pascal's Principle
• Bernoulli's Principle 

Materials that can flow and take the shape of their containers include…

• Both gases & liquids

• Liquids

• Gases

• Neither gases nor liquid

What is the SI unit use for hydraulic pressure?

• Kg/m³

• Pa

• kg m^-3

• N m²

Fluid pressure is directed

• in all directions.
• only upward.
• only downward.
• always sideways.

Air pressure is greatest:

• closer to Earth
• farther from Earth

The upward force exerted by a liquid on an object immersed in or floating on the liquid

• pressure
• buoyant force
• normal force
• gravity

The buoyant force on floating objects equals the weight of the floating object 

• true
• false

What is the equation used to calculate pressure?

• pressure= force/mass
• pressure =mass/volume
• pressure=area/force
• pressure=force/area

Atmospheric pressure increases as you move towards lower elevations and decreases as you move into higher elevations.

• True
• False
