Homework Statement
THIS PROBLEM CONSISTS OF NOTHING MORE THAN WHAT IS BEING STATED (NO VALUES, NO EQUATIONS, NOTHING) THIS IS A WORD PROBLEM WHERE NO CALCULATIONS ARE TO BE MADE: A mass hangs from a vertical spring and is initially at rest. A person then pulls down on the mass, stretching the spring. Does the total mechanical energy of this system increase, decrease or stay the same? Explain.
Homework Equations
none
The Attempt at a Solution
So what i said was the total mechanical energy of the system is constant, meaning that it stays the same (I believe this is so because one is decreasing the gravitational potential energy of the body whilst increasing the elastic potential energy such that the total mechanical energy is kept constant)
Is that right? If not, please explain to me where my interpretation of the problem has come to faults with the correct answer
