Moments, levers and gears (physics only)
Question
- A. To transmit turning effects — definition focus for physics only
- B. This confuses moment and force and does not answer Levers and gears (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: To transmit turning effects — definition focus for physics only
Explanation
The correct option is To transmit turning effects — definition focus for physics only. To transmit turning effects — definition focus for physics only is correct because it matches the approved learning objective to (Physics only) Identify input gear and output gear in simple gear diagrams. This answer belongs to Levers and gears (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
Identifying Gears
Students often confuse input gears with output gears in diagrams, leading to incorrect explanations of gear functions.
To fix this, carefully label the gears in the diagram and remember that the input gear drives the output gear, which is affected by the direction of rotation.
