Answer 1

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

Explanation: After you throw it there is no continuous upward force to balance gravity. Gravity pulls it down and aerodynamic forces (drag and insufficient lift) produce a net downward force, so the plane accelerates downward and falls.
