PS 13.2 Formative

Front

What is Bernoulli's principle?

Back

As the speed of a fluid increases, the pressure within the fluid decreases.

Front

True or False: The faster an airplane moves, the more lift the wings create.

Back

True

Front

What does Pascal's principle state?

Back

A change in pressure at any point in a fluid in a closed container is transmitted equally and unchanged in all directions throughout the fluid.

Front

What is the SI unit of pressure?

Back

Pascal (Pa)

Front

Which principle explains the operation of a hydraulic lift system?

Back

Pascal's principle.

Front

What is Archimedes' principle?

Back

An object submerged in a fluid experiences an upward buoyant force equal to the weight of the fluid displaced by the object.

Front

What is the relationship between fluid speed and pressure according to Bernoulli's principle?

Back

As fluid speed increases, pressure decreases.

Front

What is the formula for calculating pressure?

Back

Pressure = Force / Area.

Front

What is the role of lift in aviation?

Back

Lift is the force that directly opposes the weight of an airplane and holds the airplane in the air.

Front

How does the shape of an airplane wing affect lift?

Back

The shape of an airplane wing (airfoil) is designed to create a difference in air pressure above and below the wing, generating lift.
