I'm stuck with a solution to the vertical spring with a body suspended. The solution says that when the body's gravitational potential energy is decreasing, the spring's potential energy must be increasing. How is this correct?
I understand the analysis leading to the result that the vertical SHM doesn't differ from horizontal SHM, but I can't reach to that statement above. When the body moves up or down from the equilibrium position, the spring are both stretching, but the gravitational potential energy is either increasing or decreasing, right? Can someone help?
