Gravitational Potential Energy
I have a question that reads as the following:an object is dropped from the top of a high building and falls under the force of gravity alone. Which option gives the graph of the potential energy U of the object as a function of the distance x through which it has fallen?

My first instinct was for it to be a graph curving towards the x axis(like a half a rainbow)

But another one that seems feasible is a graph worth a straight line from the U(x) axis down onto the x axis
