Define speed as distance travelled per unit time.

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