| Earlier, [[183_notes:energy_cons#multi-particle_systems|you read about a puzzle involving a ball falling to the Earth]]. We resolved this puzzle by introducing [[183_notes:potential_energy|the concept of potential energy]]. In these notes, you will look an example of a person lifting a box using different choices of system. The goal here is to demonstrate that the choice of a system matters. | Earlier, [[183_notes:energy_cons#multi-particle_systems|you read about a puzzle involving a ball falling to the Earth]].
