Momentum
Question
- A. Total momentum remains constant — application focus for momentum
- B. This confuses moment and force and does not answer Momentum and force (HT 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 Momentum.
Answer
The correct answer is: Total momentum remains constant — application focus for momentum
Explanation
The correct option is Total momentum remains constant — application focus for momentum. Total momentum remains constant — application focus for momentum is correct because it matches the approved learning objective to (HT only) Link impulse-style reasoning to GCSE force and momentum explanations without introducing unsupported formulae. This answer belongs to Momentum and force (HT only) within Momentum, 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
Impulse and Momentum Confusion
Students often confuse impulse with momentum, thinking they are the same concept.
Emphasize that impulse is the change in momentum and is calculated as force multiplied by time, while momentum is mass multiplied by velocity.
