Exam-style question
Try this first
In simple harmonic motion, if the displacement is doubled, what happens to the acceleration? Scenario focus: use thermal physics in a distinct A-Level Physics context and identify the relevant physical quantity before choosing the answer.
- A.It remains the same
- B.It doubles
- C.It quadruples
- D.It halves
Model answer
What a good answer should say
- It quadruples
Explanation
Why this works
The correct answer is It quadruples. 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.
