Fluid

What does Pascal's law state?

• When you apply a small amount of pressure to a compressed fluid, it will send that pressure nowhere.

• When you apply pressure to a confined fluid, the fluid will send that pressure out in all directions at the same rate.

• When you apply a large amount of pressure to an object, it will float.

• When you use a fluid to apply pressure, the pressure will release.

The upward force exerted by a fluid is called the...

• buoyancy force
• air force
• fluidity principal
• Harry Potter's law

Water pressure increases as depth increases. 

• True
• False

Hydraulic pressure in machines takes advantage of what principal?

• Pascal's Principal
• Newton's Principal
• Water Principal

If you place an object in a fluid and it sinks which is true 

• its weight is less than the buoyant force
• the fluid is more dense than the object
• its weight  is greater than the buoyant force
• dead men tell no tales 

When a planes' wing moves through air the air over the top moves faster creating a force called 

• drag
• weight displacement
• torque
• lift 

Unit for pressure

• no
• Surface Area
• Newton
• Pascal

what is this Principle?
The buoyant fore acting on a submerged object is equal to the weight of the fluid the object displaces.

• Archimedes Principle
• newton
• All of above 

What is the equation for pressure?

• Pressure = Force / Surface area
• Pressure = Force x Surface area
• Pressure = Force + Surface area

The rule that states that a stream of fast-moving fluid exerts less pressure than the surrounding fluid.

• pascal's principle
• bernoulli's principle
• archimedes' principle
• Newton's Law
