Define "drag" in the context of rocket flight.

• A. Speed of the rocket
• B. Weight of the rocket
• C. Aerodynamic resistance experienced
• D. Altitude of the rocket

Answer: (C)

In the context of rocket flight, drag specifically refers to the aerodynamic resistance experienced by the rocket as it moves through the atmosphere. This resistance acts in the opposite direction to the rocket's motion and arises due to the interaction between the rocket's surface and the air molecules. As a rocket ascends, it encounters air resistance that can significantly affect its speed, altitude, and overall performance. Understanding drag is essential for designing rockets that can minimize resistance and optimize their flight paths. Engineers use various design strategies, such as shaping the rocket body and considering surface materials, to reduce drag, thereby improving efficiency and maximizing the altitude and speed the rocket can achieve. The other options relate to different aspects of rocket performance but do not define drag specifically.
