Question

Which statement best explains why a paper airplane eventually falls to the ground? Inertia slows the airplane and pulls it down. The unbalanced force of air resistance and gravity slow the airplane and pull it down. Inertia prevents new forces from acting on the airplane to keep it up. The force from throwing the airplane loses strength as the airplane moves.

Answer 1

The statement that best explains why a paper airplane eventually falls to the ground is: "The unbalanced force of air resistance and gravity slow the airplane and pull it down."

This explanation captures the idea that the paper airplane is affected by two main forces: gravity, which pulls it downward, and air resistance, which acts against its motion. As the plane moves forward, these forces create an imbalance that ultimately causes the airplane to lose altitude and eventually fall.
