Question

A spring is stretched from x=0x=0 to x=dx=d, where x=0x=0 is the equilibrium position of the spring. It is then compressed from x=0x=0 to x=−dx=−d. What can be said about the energy required to stretch or compress the spring?

Answer 1

The same amount of energy is required to either stretch or compress the spring.

Step-by-step explanation:

From the illustration s given in the question, it is glaring that the same amount of energy needed to stretch or expand the spring will also be the amount needed to compress it.
