Pressure

How do you Calculate Pressure

• Force(N)/Area(m²)

• Force(kg)/Area(mi²)

• Area(m²)/Force(N)

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

• increases

• decreases

• stays the same

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

• 40 N/cm²

• 100 N/cm²

• 400 N/cm²

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.

Army tank tracks are useful for travelling through the mud because..

• they decrease the force the vehicle exerts on the ground

• they increase the force the vehicle exerts on the ground

• they decrease the pressure the vehicle exerts on the ground

• they increase the pressure the vehicle exerts on the ground

How can we increase the gas pressure inside a sealed container?

• Increase the number of particles inside the container

• Increase the temperature

• Decrease the volume of the container

• All of these
