Explanation
Why this works
Stem being answered: Evaluate a student answer to Define Angular Speed And Link It To Period: what must be included for full A-Level credit? Route focus: further-mechanics-and-thermal-physics / Periodic Motion.
Key vocabulary for this item: angular, speed, link, period, frequency. Written check: state the principle, apply it to the named context, and close with the requested conclusion.
The explanation should keep the answer tied to these exact words rather than a general physics summary, using units, graph evidence or equation reasoning only when they are relevant to the stem.
