13 cards from this deck
Extension of elastic object is proportional to force (within limit of proportionality)
Point where force/extension relationship stops being linear
Max stretch point where material can still return to original shape
Material becomes permanently deformed
F=kxF = kxF=kx
Force applied to spring in Newtons (NNN)
Spring constant in Newtons per metre (Nm−1Nm^{-1}Nm−1)
Extension in metres (mmm)
Elastic region; follows Hooke's Law
Spring constant (kkk)
Plastic behaviour; does not follow Hooke's Law
Only linear line; snaps instead of stretching
Easy to stretch; lots of extension for little force
