Pressure solids

How do you Calculate Pressure

• Force(N)/Area(m²)

• Force(kg)/Area(mi²)

• Area(m²)/Force(N)

If an object's surface area is smaller does it create more or less pressure?

• More

• Less

• The same

What is pressure?

• The amount of force exerted on a surface

• The surface area of an object

• The weight of an object

A person weighs 700N and their feet have a surface area of 0.1m². How much pressure is exerted?

• 7000N/m²

• 70N/cm²

• 100N/m²

If you're walking in snow why would you wear boots instead of high heels?

• Because boots have a higher surface area making the pressure less and stopping you from sinking.

• Because it's more comfortable

• No, high heels are better

What does N/m² mean?

• Newtons per squared metre

• Kilograms per squared mile

• Squared metres per newton

Where is pressure the greatest on the dam?

• D
• C
• B
• A

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

• f ÷ a
• f x p
• p x f
• f ÷ p

Convert 10 kg to Newtons

• 0.098 N
• 4.5 N
• 100 N
• 98 N
