In aerodynamic terms, lift is directly related to the speed of the aircraft. As airspeed increases, the amount of air flowing over the wings increases, which enhances the lift generated by the wings. Conversely, when an aircraft flies at slower speeds, the airflow over the wings diminishes, resulting in a decrease in lift. This relationship is fundamentally described by the lift equation, which specifies that lift is proportional to the square of the airspeed. Therefore, at lower speeds, the reduction in airflow significantly reduces lift, supporting the assertion that lift decreases with slower speeds.

Higher drag, while a factor in overall performance, does not dictate the direct relationship between lift and airspeed; rather, drag is influenced by factors such as shape and surface area of the aircraft. The correct answer reflects the fundamental principles of aerodynamics that govern aircraft performance during various phases of flight.
