What is the relationship between the period and frequency of a vehicle moving in a circular path? Scenario focus: use angular speed in a distinct A-Level Physics context and identify the relevant physical quantity before choosing the answer.
- A.Period is the inverse of frequency.
- B.Frequency is the inverse of period.
- C.Both are directly proportional.
- D.Both are inversely proportional.
Model answer
What a good answer should say
- Both are inversely proportional.
Explanation
Why this works
The correct answer is Both are inversely proportional.. This option is correct for Periodic motion because it applies the angular speed 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.
