Reading a force-extension graph

Reading a force-extension graph

Force-extension graph with a straight Hooke's law region from the origin, a labelled limit of proportionality, the gradient labelled as spring constant, and the shaded area under the graph showing elastic strain energy

A force-extension graph shows how the stretching force on a spring, wire, or rubber band changes as it gets longer. The horizontal axis represents extension xxx, while the vertical axis represents force FFF.

Step-by-step lessons covering Edexcel A Level Physics Force-extension graphs and elastic energy for A Level Physics. Each lesson works through exam-style questions in Paper 1, Paper 2 and Paper 3 format. Physics is one of the most mathematically demanding A Levels -- at least 40% of the marks across the three papers require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
