Problem Set 11 Simple Harmonic Motion Solutions
... a) What is the potential energy inside the earth as a function of r for the object-earth system? Can you think of a natural point to choose a zero point for the potential energy? Be careful because you will need to do a work integral to determine the change in potential energy when the object moves ...
