Draw a tangent to estimate speed at a point on a curved distance-time graph.

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