If the horse reared up on 2 legs what effect would it have on the pressure?

• it will exert half the pressure it did before
• it will exert the same pressure it did before
• it will exert twice the pressure it did before
• it will exert four times the pressure it did before

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

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

Which of these animals would probably cause the greatest pressure on the ground?

• A fat cow with big feet
• A fat cow with small feet
•  A calf with big feet
• A calf with small feet

What is the equation used to calculate pressure?

• pressure= force/mass
• pressure =mass/volume
• pressure=area/force
• pressure=force/area

What is the unit of measurement for pressure?

• pascal
• grams
• milliters
• meters

Which of the following would increase the pressure on a system?

• Increase the Temperature
• Pump in more gas
• Decrease the volume
• All of these

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.

In the image which hole will allow the water to travel furthest?

• A

• B

• C

The pressure resulting from a force of 100 N exerted over an area of 5 m² is

• 20 Pa

• 0.1 N

• 10 N/m2

• 0.1 Pa
