Force Flashcards
Course along with someone or something moves
Direction
Quantity with direction and magnitude
Vector
Property of matter by which it continues and it’s existing state of rest or uniform motion the straight line unless acted on by another force
Inertia
Quantity of matter in an object regardless of his volume or of any forces acting on it
Mass
Measure force of gravity acting on the body
Weight
Force that attracts a body towards the center of the earth
Gravity
A state in which opposing forces or influences are balanced
Equilibrium
Process of doing something
Action
The response or action to or after an action
Reaction
Force equation
F=ma
Feel or appearance of a surface of an object
Texture
Extent to which a fluid resists a tendency to flow
Viscosity
Sum of all aerodynamic or hydrodynamic forces in the direction of the external fluid flow opposite of an object and overcome by thrust
Drag
This action causing friction between two objects
Rubbing
Friction you must overcome
Starting friction
Friction you must oppose to continue moving
Sliding friction
Friction isn’t dependent on because it doesn’t change the weight or texture
Surface area
Force that propels a flying machine in the direction of motion. Engines produces this
Thrust
Force that acts as a right angle to the direction of motion through the air. Created by differences in air pressure.
Lift
Force of gravity acting in a downward direction.
Weight
Force that acts opposite to direction of motion. Caused by friction.
Drag
Bernoulli
As the speed of a fluid increases, the pressure it exerts on its surroundings goes down
Upward angle from horizontal of the wings or tailplane of a fixed wing aircraft
Dihedral
Curve/bend in wing/ center of airfoil
Camber
Upward curve
Upsweep
Turning: how to turn left and right
Left-increase drag on left, increase lift on right
Right- increase drag on right, increase lift on left
Tail-define and locate
Controls nose
Nose-define and locate
Controls nose and cuts through air to control against drag/air pressure
Fuselage-define and locate
Holds structure together and accommodates passengers and cargo
Wings-define and locate
Generate lift and control airflow while flying
Engines/propellers- define and locate
Provide electric power to generate thrust to push away from plane to push it forward
Horizontal stabilizer-define and locate
Maintains planes equilibrium and stability in flight
Vertical stabilizer-define and locate
Prevents lateral moments of the aircraft
Elevators-define and locate
Increase/decrease lift on horizontal stabilizers to control motion
Rudders-define and locate
Controls motion of plane hinged to vertical stabilizer.
Ailerons-define and locate
Increase/decrease lift
tiny flaps on the wing–towards the center of the plane
Flaps
Adjusts camber of wings- increase lift at ends of wings
