Question
that they are not moving at all.
What explains the difference between what the observer is seeing and what the passenger is feeling?
A.
The observer is moving at the same velocity as the plane, so the net force on the observer is zero.
B.
The acceleration of the observer is in the opposite direction of the motion of the airplane, so the net force on the observer is decreasing.
C.
The passenger is moving at the same speed as the plane, so the net force on the passenger is zero.
D.
The acceleration of the passenger is in the same direction as the motion of the airplane, so the net force on the passenger is increasing.

When the plane accelerates forward, the passenger accelerates forward too. The seat exerts a forward force on the passenger (so there is a net force in the direction of motion), but in the passenger's accelerating frame they feel a backward (inertial) "push" into the seat. An outside observer can see no motion relative to the plane while both accelerate together, but a net forward force is still acting on the passenger.
