This document summarizes a physics laboratory experiment on potential energy conducted by students at the National University of Callao. The experiment investigated elastic potential energy using springs and gravitational potential energy by suspending masses. Tables show data on spring deformation and potential energies at different heights. Graphs plot force versus spring elongation and potential energies versus distance. The results demonstrate that elastic potential energy increases with greater spring deformation while gravitational potential energy decreases with lower elevation. The conclusion is that the total potential energy is conserved through the exchange between elastic and gravitational forms as suspended masses oscillate on springs.
