Definition of stiffness
Check what you remember
Read the wording for your board, then hide it and explain stiffness in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
A property measured by the spring constant, where a stiffer spring needs more force for the same extension and so has a larger k.
