Charlotte throws a paper airplane into the air, and it lands on the ground. Which best explains why this is an example of projectile motion?

Projectile motion occurs when an object moves horizontally while gravity pulls it vertically downward. After Charlotte throws the airplane, its forward motion continues because of inertia, while gravity makes it descend to the ground. So the best explanation is that the airplane’s motion is due to horizontal inertia and the vertical pull of gravity.
