Bernoulli’s principle
pressure decreases as a fluid speeds up
pressure increases as a fluid speeds up
pressure remains constant regardless of fluid speed
pressure decreases as a fluid slows down
pressure
the amount of force exerted on a certain area
the total weight of an object
the speed of a moving object
the distance between two points
drag
the backward force on an aircraft caused by friction
the upward force that opposes gravity
the forward thrust produced by engines
the lateral movement of an aircraft during flight
Archimedes’ principle
a submerged object is pushed upward by a force equal to the weight of the fluid it displaces
an object will float if it is less dense than the fluid
the pressure in a fluid increases with depth
the buoyant force is always equal to the weight of the object
thrust
the force that pushes an aircraft forward
the resistance that opposes motion
the lift generated by the wings
the weight of the aircraft
buoyant force
the upward force exerted by a fluid
the downward force exerted by a fluid
the force that opposes gravity
the force that increases with depth
Pascal’s principle
pressure is transferred equally throughout a fluid in all directions
pressure increases with depth in a fluid
pressure is inversely proportional to volume
pressure is dependent on the shape of the container
airfoil
an object whose shape contributes to lift
a type of bird
a tool for measuring air pressure
a device for cooling engines
hydraulic system
a system that uses fluids to increase or transfer forces
a mechanical system that relies on gears and levers
a system that uses air pressure to operate machinery
a type of electrical circuit that controls fluid flow
air pressure
the force exerted by air
the weight of air in the atmosphere
the temperature of the air
the movement of air particles
lift
the force that pushes an aircraft up
the weight of the aircraft
the speed of the aircraft
the drag force acting on the aircraft
weight
the downward force on an object caused by gravity
the mass of an object
the amount of space an object occupies
the force exerted by an object in motion
