Exam-style question
Try this first
A car is moving in a circular path with a radius of 50 meters. If the car completes one full revolution in 10 seconds, calculate the angular speed of the car in radians per second. 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 speed of the car is 0.628 radians per second.
Explanation
Why this works
The correct answer is The angular speed of the car is 0.628 radians per second.. 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.
