5.5.151 - Free and forced oscillations

Understand the distinction between free and forced oscillations.

Use - free and forced oscillations to connect the rule to the data and decision in the question.

This matters because - free and forced oscillations determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply - free and forced oscillations to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: - Free and forced oscillations is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
