Homework Help: Physics

Posted by Kathrine on Wednesday, December 17, 2008 at 7:58pm.

How is it possible for gravitational potential energy to be negative?
I Googled the answer, but all I could understand was that if the PE was zero at infinity as you move toward an object with gravity the KE must be positive because KE is the energy of motion so the the PE must be negative to equal a total of zero. Is this right? Or am I way off the mark?
