Force and Pressure

What is the unit of measurement for pressure?

• pascal
• grams
• milliters
• meters

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)

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.

What is pressure?

• The amount of force exerted on a surface

• The surface area of an object

• The weight of an object

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.
