Pressure and Pascal's Principle

The amount of force pushing on an area is the definition of....

• Fluid

• Viscosity

• Barometer

• Pressure

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

A force is applied in a closed container, the pressure increases the same amount. EX: squeezing a water bottle or toothpaste

• Archimede's Principle

• Pascal's Principle

• Bernoulli's Principle 

Pressure can be measured in Pascals (Pa) or Newtons per square meter.

1 Pa = 1N/m²

• True

• False

Which comparison is correct

• F1 = F2

• P1 > P2

• F1 > F2

• P1 = P2

What is the pressure in the hydraulic fluid?

• 1210 N

• 484 N/m²

• 8000 N

• 3025 N/m²

What principle is this hydraulic press showing?

• Archimedes' Principle

• Bernoulli's Principle

• Pascal's Principle

• Principle Testa

What is the force up on the mailbox?

• 1210 N

• 8000 N

• 7744 N

• 5655 N
