Forces in Fluids

What do we call the the amount of force exerted on a certain area?

• fluid
• pressure
• buoyant

When pressure is applied to a confined fluid, the increase in pressure is transmitted equally to all parts of the fluid. This fact is called________.

• Pascal's Principle

• Newton's Principle

• Archimedes' Principle

• Bernoulli's Principle

Bernoulli's principle creates ___ in airplanes

• Drag

• Lift

• Weight

• Friction

The force that opposes or restricts motion in a fluid is called?

• thrust

• lift

• turbulence

• drag

What is a fluid?

• a non-solid state of matter as a gas or a liquid.

• A solid state of matter as an object

• the pressure caused by the weight of the atmosphere

The pressure caused by the weight of the atmosphere is called what?

• pascal

• atmospheric pressure

• pressure

• force

In which direction is fluid pressure directed?

• Up

• Down

• Sideways

• In all directions

The principle that states that the buoyant force of an object in a fluid is an upward force equal to the weight of the volume of the displaced fluid.

• Bernoulli’s

• Archimedes’

• Hodder’s

• Nelson's

One application of Pascal's principle is

• a hydraulic car lift

• the flight of an airplane

• a speedboat's bottom slapping against the waves

• the buoyancy shown by ducks and other waterfowl

If an object floats, the volume of displaced water is equal to the volume of

• the entire object

• the portion of the object that is above water

• the portion of the object that is submerged

• exactly half of the object
