I was wondering which equation do springs obey better:
$$F=-kx$$
$$F=-k ln(x/x_0)$$
The first is Hooke's law, but the second comes when we consider the relative deformation instead of the absolute deformation. I am asking because I haven't seen any website stating the second equation, I just got it when I integrated the relative strain equation.
