A student is asked to describe the path of a paper airplane that is thrown in the classroom.

Which statement best describes the path of the paper airplane?

The paper airplane will move in a straight line, according to Newton’s first law of motion.
The paper airplane will drop straight to the ground once its inertia gives in to the force of gravity.
The paper airplane will create a curved path toward the floor as it is pulled toward Earth’s center.
The paper airplane will orbit around the desk because it is the object with the largest mass in the room.

The statement that best describes the path of the paper airplane is:

The paper airplane will create a curved path toward the floor as it is pulled toward Earth’s center.

This statement recognizes that while the airplane may initially be thrown in a straight line, gravity will act on it, causing it to follow a curved trajectory downward. The other statements either incorrectly simplify the airplane's motion or misunderstand the effects of mass and inertia.
