A mass is hanging on the end of a spring and oscillating up and down. There are three forces acting on the mass, the force of the spring, the force of gravity, and the force of air resistance. Which of these forces can be associated with potential energy function?

a. the spring force only
b. gravity only
c. the spring force and gravity
d. all three forces
