A vehicle in motion will have inertia - one which isn't moving will not.
Increasing speed is acceleration. Some examples include: 1. A car speeding up (accelerating) from a parked position to 30mph. 2. A person speeding up to a walking pace from a sitting position. 3. An airplane speeding up from its runway position to its speed at lift-off.
The correct term is 'flew in an airplane" because it means you were in the plane and on the plane means you were literally sitting on the fuselage of the plane.
Yes
This depends on what you're trying to say. "On the airplane" implies that something is literally on the outside of the airplane, such as the logo, paint, or something sitting on the wings. "In the airplane" usually means that something is inside, such as cargo and people. However, sometimes people do say "He is on the airplane" to mean that he is a passenger or crew member -- this is not technically correct, but it has come to be common usage.

To sit next to your family or friend. Or because you don't like who you are sitting by.
No, the weight of the airplane will not change when birds fly inside. The weight of the airplane is determined by factors like the total mass of the plane, fuel, cargo, and passengers - the presence of birds inside will not significantly impact this total weight.
Sitting in our airplane seats farmland passes below.
Those seagulls would weigh two pounds whether they were sitting in the airplane or flying in it. This is because they have push the air below them (in the airplane) down with two pounds of force to keep two pounds in the air. So, yes, the seagulls would add 2000 pounds to the airplane's weight.
The center of gravity is a point on the airplane that the airplane would balance while sitting on the ground. The center of gravity or also called "the CG" is important in trimming the aircraft in flight as the weight has to balance out the forces on the wing. It is also important in aerodynamic maneuvers as the G-forces act through CG.
Once above the clouds there is nothing to separate you from space which is obviously black. The only thing that can brighten it up is the sun...
Johnson was sworn in while the plane was sitting on the ground in Dallas. When it took off, it headed for Washington, DC.
