Which statement best explains why a paper airplane eventually falls to the ground

Question

The unbalance forces of air resistance in gravity slow the airplane and pull it down

Inertia slows the airplane and pulls it down

The force from throwing the airplane loses strength as the airplane moves

The force from throwing the airplane loses strength as the airplane moves

Inertia prevents new forces from Acting on the airplane to keep it up

Answer 1

The statement that best explains why a paper airplane eventually falls to the ground is:

The unbalance forces of air resistance and gravity slow the airplane and pull it down.

This statement acknowledges that while the airplane experiences a force from being thrown (thrust), it also encounters air resistance (drag) that opposes its motion. Gravity continuously pulls it downward. As the thrust decreases and the forces become unbalanced, the paper airplane will eventually lose altitude and fall to the ground.
