LECTURE 27: Gravitational potential energy
... As seen in the practice problem above, the work from the force of gravity is the same regardless of which path the object traversed. We can generalize further and claim that no matter what path, no matter how silly it may be, the work from the force of gravity on an object is independent of the path ...
