If a mechanical system has very low damping, what characteristic describes its resonant response peak?

Answer

A very sharp, high-peak response right at the natural frequency, associated with a high Q-factor.

Low damping means very little energy is lost per cycle, allowing the amplitude to build sharply and reach a high peak precisely at the natural frequency, which corresponds to a high Quality Factor (Q-factor).
