Quiz - Chapter 6: Pressure (12/3)

How do you Calculate Pressure

• Force(N)/Area(m²)

• Force(kg)/Area(mi²)

• Area(m²)/Force(N)

Why won't you sink in mud if you wear boots?

• Because the surface area is larger creating less pressure.

• Has air in it to keep you floating.

• Because the mud won't want you.

Diagram shows the design of a dam. Why does the thickness of the dam increase with its depth?

• The design of this structure is stronger.

• Water pressure increases with depth.

• The cost of construction is lower.

• Water pressure acts uniformly in all directions.

Pressure can be exerted by solids, liquids and gases.

• TRUE

• FALSE

This is an example of the everyday application of pressure in:

• Solids

• Liquids

• Gases

• Plasma

(True or False.) Air resistance is caused by friction between the air and an object moving through the air.
