Interpret a horizontal line on a velocity-time graph as constant velocity.

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