According to Newton's 1st Law of Motion, _________.
Any object has a tendency to continue what it is doing until some external force acts on it
As the velocity of a fluid (such as air) increases, its pressure decreases
An airfoil pattern causes a downward flow of air behind the wing called downwash
Acceleration is produced when an unbalanced force acts on an object
Bernoulli's Principle theorized ______________.
Any object has a tendency to continue what it is doing until some external force acts on it
Weight is the force on an object caused by the downward pull of gravity
As the velocity of a fluid (such as air) increases,
Every force applied to an object is opposed by an equal force in the opposite direction
______________ is any surface, such as a wing, which provides aerodynamic force when it interacts with a moving stream of air.
A UAV
A Venturi Tube
An airfoil
An airframe
___________ means the airplane is maintaining a constant airspeed and is neither accelerating nor decelerating.

Thrust
None of the choices are correct
__________ is the force on an object caused by the downward pull of gravity.
Lift
