Unit 7: Pressure & Fluids

This is the force per unit area applied to the surface area of an object:

• Force

• Pressure

• Area

• Gravity

The SI unit for pressure is:

• Newtons

• Grams

• Pascals

• PSI (Pounds/inch2)

One Pascal is equal to:

• 1 N/ m²

• 1 kg x m/s²

• 1 g / cm³

• 1 lb/ in²

Two ways to increase pressure are:

• Increase force and increase surface area

• Decrease force and increase surface area

• Decrease force and decrease surface area

• Increase force and decrease surface area

A kPa is equal to:

• 100 Pascals

• 1000 Pascals

• .001 Pascals

• .01 Pascals

Area =

• Length x Width x Height

• 1/2 Base x Height

• Length x Width OR Base x Height

• Force x Acceleration

Pressure =

• Force / Area

• Force x Area

• Force x Acceleration

• Area / Force

Force =

• Pressure / Area

• Area / Pressure

• Pressure x Area

• Pressure x Acceleration

Area =

• Force / Pressure

• Pressure / Force

• Pressure x Force

• Length x Width x Height

What is the area of a rug that is 4 meters long by 2 meters wide?

• 2 m²

• 0.5 m²

• 6 m²

• 8 m²
