Moments, levers and gears (physics only)
Question
- A. 20 Nm — application focus for moment
- B. This confuses moment and force and does not answer Moments and turning effects (physics only).
- C. This is too vague because it does not use the force or motion quantity named in the objective.
- D. This reverses the physical cause and effect for Moments, levers and gears (physics only).
Answer
The correct answer is: 20 Nm — application focus for moment
Explanation
The correct option is 20 Nm — application focus for moment. 20 Nm — application focus for moment is correct because it matches the approved learning objective to (Physics only) State that moment is measured in newton metres. This answer belongs to Moments and turning effects (physics only) within Moments, levers and gears (physics only), so it must use precise AQA GCSE Physics forces and motion vocabulary. The other options are wrong because they either confuse moment and force, omit the required force or motion condition, or move away from the exact subtopic being tested.
Common mistake
Misunderstanding Moment Units
Students often confuse the unit of moment, stating it as newtons instead of newton metres.
Remember that moment is defined as the turning effect of a force and is measured in newton metres (Nm), which combines force (N) and distance (m) from the pivot.
