Plot a force-extension graph using appropriate scales and units.

In the subtopic Required practical: force and extension, this learning objective focuses on plot a force-extension graph using appropriate scales and units. For AQA GCSE Physics 8463 Unit 4.5 Forces, keep the explanation inside Required practical: force and extension and Forces and elasticity. Approved keywords for this objective include graph, force, and extension. A strong answer separates scalar and vector quantities, uses correct units where quantities are involved, and links the physical reasoning back to plot a force-extension graph using appropriate scales and units. This is not a generic revision point: it is specifically about Required practical: force and extension, Forces and elasticity, and the approved wording of the learning objective.
