How do you Calculate Pressure

• Force(N)/Area(m²)

• Force(kg)/Area(mi²)

• Area(m²)/Force(N)

What is pressure?

• The amount of force exerted on a surface

• The surface area of an object

• The weight of an object

What is the unit of measurement for pressure?

• pascal
• grams
• milliters
• meters

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

Pressure can be measured in Pascals (Pa) or Newtons per square metre.
1 Pa = 1N/m2

• True
• False

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

• f ÷ a
• f x p
• p x f
• f ÷ p

Pressure is measured in what units

• Newtons
• m/s
• Pascals
• Moles

Pressure is equal to force divided by what

• area
• mass
• time
• distance

The pressure resulting from a force of 50 N exerted over an area of 5 m² is

• 10 N
• 0.1 N
• 10 N/m2
• 0.1 Pa
