Question
- A. To collect motion data accurately — graph focus for light gate
- B. This confuses scalar and vector quantities and does not answer Required practical: acceleration.
- 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 Forces and motion.
Answer
The correct answer is: To collect motion data accurately — graph focus for light gate
Explanation
The correct option is To collect motion data accurately — graph focus for light gate. To collect motion data accurately — graph focus for light gate is correct because it matches the approved learning objective to use light gates, data loggers or ticker timers to collect motion data. This answer belongs to Required practical: acceleration within Forces and motion, 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 Data Collection Tools
Students often confuse the functions of light gates, data loggers, and ticker timers, thinking they all serve the same purpose in collecting motion data.
Clarify that light gates measure the time an object passes through them, data loggers record data continuously over time, and ticker timers produce a series of dots on tape to indicate motion over intervals.
