| Remember that the potential energy change is the negative change in the internal work ($\Delta U = -W_{int}$). So, you can calculate what the work done by the gravitational force would be and use that to determine that change in potential energy in going from location 1 to location 2, | Remember that the potential energy change is the negative change in the internal work ($\Delta U = -W_{int}$).
