CAIE IGCSE Physics 1.5.1.2 Load–extension graphs for an elastic
Practise reading spring and elastic-solid data, finding extension, and linking straight-line load-extension graphs to Hooke's law.
How this is tested
- find extension from length and unstretched length in a spring data table
- read a load-extension graph to determine an unknown weight or initial length
- sketch or recognise a straight line through the origin for Hooke's law
