LSS Pressure

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

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

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

Pressure decreases when the surface area over which a force is applied increases

• True
• False

Look at the pressure triangle. How do we calculate the area?

• f ÷ a
• f x p
• p x f
• f ÷ p
