Fluids Review

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 pressure is distributed equally to all parts of the fluid. This idea is...

• Pascal's Principle

• Newton's Principle

• Archimedes' Principle

• Bernoulli's Principle

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

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

What causes the apparent weight loss of an object immersed in water?

• Gravity
• Buoyancy
• Newton's 1st law
• Newton's 2nd law

Bernoulli's principle creates ___ in airplanes

• Drag
• Lift
• Weight
• Friction

When drinking soda from a straw, the soda rises up the straw because....

• you lower the pressure in the straw and the atmosphere pushes the soda up
• you raise the pressure in the straw and the atmosphere pushes the soda down

If an object sinks in a fluid, _____.

• the object is more density than the fluid

• the object is less dense than the fluid

Hydraulic lifts take advantage of what principal?

• Pascal's Principal

• Newton's Principal

• Water Principal

The ability of a fluid to exert an upward force on an object is known as

• pressure
• viscosity
• buoyancy

States that as the velocity of a fluid increases, the pressure decreases.  This causes planes to fly . 

• Archimedes' Principle
• Bernoulli's Principle
• Pascal's Principle
