28. Aerodynamics
Aerodynamics concerns the motion of air and other gaseous fluids and other forces acting on objects in motion through the air (gases).
In effect, Aerodynamics is concerned with the object (aircraft), the movement (Relative Wind), and the air (Atmosphere).

29. Newton’s Laws of Motion
Newton's three laws of motion are:
Inertia - A body at rest will remain at rest. and a body in motion will remain in motion at the same speed and direction until affected by some external force.
Nothing starts or stops without an outside force to bring about or prevent motion. Hence, the force with which a body offers resistance to change is called the force of inertia.

30. Newton’s Laws of Motion
Newton's three laws of motion are:
Acceleration - The force required to produce a change in motion of a body is directly proportional to its mass and the rate of change in its velocity.
Acceleration refers either to an increase or a decrease in velocity, although Deceleration is commonly used to indicate a decrease.

31. Newton’s Laws of Motion
Newton's three laws of motion are:
Action / Reaction - For every action there is an equal and opposite reaction.
If an interaction occurs between two bodies, equal forces in opposite directions will be imparted to each body.

32. Who is Daniel Bernoulli?
Dutch-born physicist – born in 1738
Discovered a relationship between the pressure and speed of a fluid in motion
Specifically – as velocity of a fluid increases, the pressure decreases

33. Who is Daniel Bernoulli?
For Lift to occur - The pressure on top of the airfoil must be less than the pressure below.
The airfoil has no choice but to move upward.

34. Who is Daniel Bernoulli?
Camber determines the amount of lift an airfoil will produce at a given speed
The thicker or more pronounced the camber – the more lift.
At low speeds its best to have a high-lift airfoil.
