Define thinking distance as the distance travelled during the driver's reaction time.

In the subtopic Stopping distances and safety, this learning objective focuses on define thinking distance as the distance travelled during the driver's reaction time. For AQA GCSE Physics 8463 Unit 4.5 Forces, keep the explanation inside Stopping distances and safety and Forces and motion. Approved keywords for this objective include thinking distance and reaction time. A strong answer separates distance and displacement, uses correct units where quantities are involved, and links the physical reasoning back to define thinking distance as the distance travelled during the driver's reaction time. This is not a generic revision point: it is specifically about Stopping distances and safety, Forces and motion, and the approved wording of the learning objective.
