Lab Six: Work and Energy Purpose: In this lab, our goal is to understand the work done by a constant force and variable force. Also, our goal is to see how gravitational potential energy is stored in a mass and how elastic potential energy is stored in a spring. Finally, from all of this experimentation, we hope to fully understand the Work- Energy Theorem.
