SUMMARY
A simple pendulum and a mass oscillating on a spring each exhibit one normal mode of oscillation, characterized by simple harmonic motion. This means that both systems have a single natural frequency at which they oscillate most effectively. The analogy of a person on a swing illustrates this concept, as there is an optimal rate of swinging that maximizes amplitude. In contrast, systems like musical strings and wind instruments possess multiple normal modes and frequencies.
