Exam-style question
Try this first
In a simple harmonic motion system, the maximum displacement (amplitude) is 0.5 m and the maximum velocity is 2 m/s. Calculate the angular frequency of the system. Scenario focus: use thermal physics in a distinct A-Level Physics context and identify the relevant physical quantity before choosing the answer.
Model answer
What a good answer should say
- The angular frequency is 4 rad/s.
Explanation
Why this works
The correct answer is The angular frequency is 4 rad/s.. This option is correct for Periodic motion because it applies the thermal physics idea in the stem and keeps the relevant quantity, unit, and physical conclusion together.
The alternatives either use a neighbouring formula, omit a required variable, or describe a different physical situation.
