Momentum
Question
- A. By increasing collision time — definition focus for force
- 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: By increasing collision time — definition focus for force
Explanation
The correct option is By increasing collision time — definition focus for force. By increasing collision time — definition focus for force is correct because it matches the approved learning objective to (HT only) Explain how airbags increase collision time to reduce force on passengers. 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
Misunderstanding Airbag Functionality
Students often think that airbags prevent collisions rather than reducing the force experienced by passengers during a collision.
Emphasize that airbags increase the time over which the collision occurs, thereby reducing the force on passengers according to the relationship between force, change in momentum, and time.
