Question

# Needed help with these questions: The questions may have words or graphs that

tell you things about the motion and then ask you to what energies are changing and how you know this. Or, it may tell you something about the motion and ask you to produce graphs of energy vs position. It might give you some numbers and ask you to calculate one or more other numbers and then explain how you did this.
