Fluid Principles

The upward force exerted by a fluid on a submerged object.

• gravity

• anti-gravity

• buoyant force

• lift

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

A system that multiplies force by transmitting pressure from a small surface area through a confined fluid to a larger surface area.

• hydraulic system

• archimedes system

• pressure system

• bernoulli effect

An object is buoyed up when

• the buoyant force is less than the object's weight.

• the buoyant force is greater than the object's weight.

• the buoyant force equals the object's weight.

• there is high air pressure.

The brake pedal is very small but the driver is able to stop the car because when pressing on the pedal 

• the pressure is exerted evenly through the fluid to all 4 brake pads.

• Pascal's principle is being demonstrated.

• this is hydraulics in action!

• all of these options.

Due to Bernoulli's principle, the pressure is ____ above an airplane's wing than below it.

• Lower

• Higher

An upward force.

• lift

• gravity

• life

• drag

Which direction does buoyant force always push?

• downward

• upward

• all directions

• sponge bob

Fluid pressure is directed

• in all directions.

• only upward.

• only downward.

• always sideways.

Fluids flow

• only when warmed up.

• from regions of low pressure to regions of high pressure.

• until evenly spread out.

• from high to low pressure.
