3.3 Section Review

Define pressure.

How do you Calculate Pressure

• Force(N)/Area(m²)

• Force(kg)/Area(mi²)

• Area(m²)/Force(N)

What is the unit of measurement for pressure?

• pascal
• grams
• milliters
• meters

Pressure can be measured in Pascals (Pa) or Newtons per square metre.
1 Pa = 1N/m2

• True
• False

A fluid can be...

• a gas
• a liquid
• a liquid or a gas
• a solid

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

• Substance
• Fluid
• Pressure
• Displacement

Archimedes' principle states that the weight of the fluid an object displaces is equal to the buoyant force acting on the object. 

• True
• False

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

• Float

• Shrink

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

• Expand
• Shrink
• Float
• Sink

Archimedes' principle addresses
