Do fins placed forward of the center of gravity stabilize an unguided rocket during flight?

Fins placed forward of the center of gravity do not stabilize an unguided rocket during flight because stability is achieved when the center of pressure is located behind the center of gravity. When fins are positioned ahead of the center of gravity, they can create an unstable situation. This occurs because any tendency of the rocket to rotate will cause the center of pressure to push further away from the center of gravity, exacerbating the rotation instead of countering it.

In contrast, for an unguided rocket to maintain a stable flight path, it is essential for the fins to be mounted behind the center of gravity. This positioning allows the airflow around the rocket to exert corrective forces on the tail, helping to keep the rocket aligned with its flight path and preventing it from spiraling or veering off course.

The other choices imply scenarios where either size or speed might influence stability, which doesn't apply to the fundamental aerodynamic principles governing rocket flight stability. Keeping the center of pressure below the center of gravity is vital regardless of the rocket's size or speed for effective stabilization.
