Homework Statement
I know that potential gravitational energy is relative to the reference point that I decide to choose (like in the picture below).
But then if, for instance, I set my reference point in the ceiling and my vertically down y-axis to be positive. What would the potential gravitational energy of an object falling from the ceiling and an object moving towards the celing be? This kind of makes me confused. I'd appreciate some insight on this matter.
