Springs are generally modeled as being elastic and following Hooke's law. So a potential energy function can be defined: ##PE = \frac{1}{2}k x^2##.

Ropes, on the other hand, are generally modeled as being inelastic and inextensible. (Obviously a simplification, as real ropes often do stretch appreciably under load.)
