Question
- A. Energy is transferred to thermal stores — definition focus for braking
- B. This confuses scalar and vector quantities and does not answer Energy transfer and braking.
- 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: Energy is transferred to thermal stores — definition focus for braking
Explanation
The correct option is Energy is transferred to thermal stores — definition focus for braking. Energy is transferred to thermal stores — definition focus for braking is correct because it matches the approved learning objective to explain that braking often transfers energy to thermal stores in brakes and surroundings. This answer belongs to Energy transfer and braking 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 Energy Transfer in Braking
Students often confuse the energy transferred during braking with the total kinetic energy of the vehicle, failing to recognize that energy is dissipated as thermal energy in the brakes and surroundings.
To fix this, students should focus on the concept that braking forces do work on the vehicle, transferring energy from the kinetic energy store to thermal stores, and practice explaining this process clearly.
