Momentum
Question
- A. The force decreases — definition 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: The force decreases — definition focus for momentum
Explanation
The correct option is The force decreases — definition focus for momentum. The force decreases — definition focus for momentum is correct because it matches the approved learning objective to (HT only) Describe how increasing impact time reduces the force for the same change in momentum. 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
Impact Time and Force Misunderstanding
Students often think that increasing impact time always increases the force experienced during a collision.
Emphasize that increasing impact time actually reduces the force for the same change in momentum, as force is related to the rate of change of momentum.
