Archimedes Principles explains how a steel ship can stay afloat.
True
False
More dense objects will float on less dense objects.
True
False
Pascal's Principle explains how hydraulic fluid can be used to move pistons on the bed of dump trucks.
True
False
A unit of pressure is called a
bernoulli
pascal
pound
meter
Which type of substance does Pascal's principle deal with?
solids
fluids
powders
metals
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
Which of the following is true of the buoyant force?
it acts in the downward direction
it acts with the force of gravity
it acts in the upward direction
ti makes an object feel heavier
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
What scientific rule states that the buoyant force on an object is equal to the weight of the fluid displaced by the object?
Archimedes' principle
Pascal's principle
Bernoulli's principle
Newton's third law of motion
A ship stays afloat as long as the buoyant force is
less than the ship's weight
equal to the ship's weight
less than the ship's speed
greater than the ship's speed
The mass per unit volume of a substance is its
density
buoyancy
weight
fluid pressure
An object that weighs more than the water it displaces will
sink in water
float in water
neither sink nor float
alternate sinking and floating
This principle says that an increase in pressure on a confined fluid is transmitted equally to all parts of the fluid.
Newton's Principle
Bernoulli's Principle
Archimedes' Principle
Pascal's Principle
This principle states that the faster a fluid moves, the less pressure the fluid exerts.
