What is aerodynamics?

Aerodynamics is the study of the properties of moving air and solid bodies moving through it.

At about how many degrees does a plane reach its critical angle of attack?

15 degrees

What is an example in aviation or Newtons third law in action?

Jet propulsion - a driving or propelling force in which a has turbine provides the thrusting power.

The speed of relative wind depends on the aircraft's speed and what else?

The direction it is flying.

In what year was the first manned balloon flight?

What edge of an airfoil is rounded? Which is sharp?

What is another name for Newtons first law?

The law of intertia (states that a body in motion tends to stay in motion and a body at rest tends to stay at rest).

What did the Wright brothers discover using a wind tunnel?

They discovered which airfoil shape produced the most lifting force.

Why does an airfoils shape create a lifting force?

When air flows over the curved upper surface of the wing, it speeds up. This reduces pressure above the wing and produces an upward lifting force.

What does F=ma mean?

force=mass x acceleration
