Purpose: To investigate experimentally the extension of a spring and how it is related to the applied force, and recall that the extension of a spring is directly proportional to the force applied ...

The extension is the new length minus the unloaded length. Figure caption, Graph showing Hooke's Law, force is plotted against extension Provided that the limit of proportionality is not exceeded ...

A series of lessons on Hooke’s law is likely to include: experimental design; setting up and using equipment; collecting numerical data using a range of devices; recording and presenting data, ...
