Quiz on Pressure Concepts

What is the formula for calculating pressure?

• Pressure = Area ÷ Force

• Pressure = Force ÷ Area

• Pressure = Force × Area

• Pressure = Force + Area

Which of the following affects pressure?

• Force only

• Area only

• Both force and area

• Neither force nor area

A box weighing 100 N is placed on a surface with an area of 5 m². What is the pressure it exerts on the surface?

• 5 Pa

• 20 Pa

• 50 Pa

• 500 Pa

High heels exert more pressure on the ground than flat shoes because:

• High heels are lighter.

• High heels have a smaller area of contact.

• High heels are made of harder material.

• High heels increase the wearer’s weight.

Pressure in a liquid increases with:

• Decreasing depth

• Increasing depth

• Increasing temperature

• Decreasing temperature

Why does a balloon pop when it is overinflated?

• The particles inside the balloon move slower.

• The particles inside the balloon create less pressure.

• The particles inside the balloon exert too much pressure.

• The temperature of the balloon decreases.

What causes pressure in liquids and gases?

• Gravity pulling the particles down.

• Particles colliding with each other and surfaces.

• The temperature of the particles.

• The density of the particles only.

Which situation shows how pressure is reduced?

• A nail being hammered into wood.

• A knife being used to cut vegetables.

• A camel walking on sand with wide feet.

• A woman walking in high heels.

Why do large trucks have wider tires?

• To increase the force on the road.

• To decrease the force on the road.

• To increase the pressure on the road.

• To decrease the pressure on the road.

A hydraulic system has a small piston with an area of 0.05 m² and a large piston with an area of 1 m². If a force of 500 N is applied to the small piston, what is the force exerted by the large piston?

• 500 N

• 5,000 N

• 10,000 N

• 1,000 N
