Course coverage and review details

The official topic states no explicit exclusions and defines natural frequency as the frequency of a system in free oscillation. Ideal SHM uses a linear restoring relation and no environmental energy exchange; damping and steady forced response are introduced only when stated.

Coverage is reviewed against 9478 topic 9(a)–(l), PDF page 18. Selected-response progress does not by itself prove constructed, diagrammatic or practical performance.
