Exam-style question
Try this first
In a simple harmonic oscillator, if the amplitude is doubled, what happens to the maximum potential energy? Scenario focus: use simple harmonic motion 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 reduces by half.
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 simple harmonic motion 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.
