Physical Science - Chapter 7 Review

Front

What is Pascal's Principle?

Back

A principle stating that a fluid contained in a vessel exerts pressure of equal size in all directions.

Front

What does Bernoulli's Principle state?

Back

As the speed of a moving fluid increases, its pressure decreases.

Front

From where do all fluids flow?

Back

All fluids flow from high pressure to low pressure.

Front

What is the primary force that gives air pressure?

Back

Gravity.

Front

What is a fluid?

Back

Any material that can flow and take the shape of its container.

Front

Define Drag in fluid dynamics.

Back

The resistance experienced by an object moving through a fluid.

Front

What is Lift in the context of fluid dynamics?

Back

The force that directly opposes the weight of an object and holds it in the air.

Front

What is Thrust?

Back

The force that propels an object forward, often produced by engines.

Front

Explain Archimedes' Principle.

Back

A principle stating that an object submerged in a fluid experiences a buoyant force equal to the weight of the fluid displaced.

Front

What is the Buoyant Force?

Back

The upward force exerted by a fluid on an object submerged in it.
