Objectives: Students will become familiar with the concepts of work , conservative forces and potential energy . In addition, they will become acquainted with the principle of virtual work . After studying this chapter, students should be able to correctly apply this principle in order to determine...
and I'm pretty sure potential energy is not neccissarly the same as work done. It's the negative of the change in PE that is the same as work done by a conservative force (like a spring, which is the case here) Also if the was the case wouldn't the spring constant reach it...
