Explain why identical objects at the same height would have different gravitational potential energies on different planets

To calculate the the gravitational potential energy for an object, we use the equation: PE = mgh In this equation, PE is potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height. Since different planets have different values for g, the potential energy for identical objects at the same height could be different, because the value of g is different for different planets.
