A lot of problems I see have vertical mass-spring systems, where a mass m hangs from a spring with spring constant k stretching it a distance D, and usually all but one of those quantities is known. But would you equate the forces or the energies, i.e. which is the correct equation to use: mg=kD or mgD = 1/2kD^2, because the two give different answers.
Which is correct? Why is the other incorrect?
Thank You
