Deformation
Explain why deformation requires interacting forces and distinguish elastic from permanent deformation.
Distinguish extension from total length and elastic limit from limit of proportionality.
Hooke's law
Use and rearrange the linear spring equation with correct force, extension and spring-constant units.
Explain stiffness and proportional force-extension relationships and convert hanging masses to load forces.
Graphs and energy
Interpret force-extension graphs, calculate linear gradients and recognise axis-order effects and proportionality limits.
Distinguish non-linear elastic behaviour from inelastic deformation using unloading evidence.
Calculate elastic energy using squared extension and explain the linear-range assumption.
Determine work from force-extension area and explain why linear loading gives a triangle rather than final-force times extension.
Spring practical
Describe controlled spring loading and unloading with original-length readings, stable measurements, repeats and safe support.
Use best-fit graph gradients and areas to determine stiffness and work, accounting for limits and measurement uncertainty.
