• Force exerted on a given area of surface

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

Where would you find the largest pressure?

• At the bottom of the ocean

• At the top of Jebel Jais

• Close to ground on a drifting track

• At the bottom of Jebel Jais

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

When force increases...

• pressure increases

• pressure decreases

• pressure stays the same

• pressure increases then decreases
