1. The problem statement, all variables and given/known data These relate to a Hooke's law lab involving springs. What are the differences between ideal springs and real springs. Also, does anyone know why applied force is plotted on the vertical axis of a graph while x (change in displacement from equilibrium) is plotted on the horizontal even though Fx is the independent variable? 2. Relevant equations Fx= k x 3. The attempt at a solution I know that ideal springs face no internal or external friction while real springs do but not much other than that. As for the second question, I'm stumped.
