pressure

When you increase your depth under water, the water pressure on your body

• increases

• decreases

• stays the same

What decreases as you go up in the atmosphere?

• Altitude
• Atmosphere
• Meteors
• Air Pressure

How do you Calculate Pressure

• Force(N)/Area(m²)

• Force(kg)/Area(mi²)

• Area(m²)/Force(N)

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.

What is pressure?

• The amount of force exerted on a surface

• The surface area of an object

• The weight of an object

What is the unit of measurement for pressure?

• pascal
• grams
• milliters
• meters

An object will float on water if it is

• less dense than water.

• more dense than water.

• the same density as water.

What pressure does a 4000N horse exert on the ground if each foot is 10cm²?

• 40 N/cm²
• 100 N/cm²
• 400 N/cm²
• 10 N/cm²

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
