Work done and energy transfer
Question
- A. 1 joule — definition focus for work done
- B. This confuses scalar and vector quantities and does not answer Work done by a force.
- 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 Work done and energy transfer.
Answer
The correct answer is: 1 joule — definition focus for work done
Explanation
The correct option is 1 joule — definition focus for work done. 1 joule — definition focus for work done is correct because it matches the approved learning objective to explain that work done against friction transfers energy to thermal stores. This answer belongs to Work done by a force within Work done and energy transfer, so it must use precise AQA GCSE Physics forces and motion vocabulary. The other options are wrong because they either confuse scalar and vector quantities, omit the required force or motion condition, or move away from the exact subtopic being tested.
Common mistake
Misunderstanding Work Done Against Friction
Students often confuse the concept of work done against friction with the total energy transferred, failing to recognize that this work specifically results in energy being transferred to thermal stores.
To fix this, students should focus on the definition of work done as energy transferred when a force moves an object, and specifically understand that work done against friction leads to an increase in thermal energy.
