Hi all,
being a long time since i last posted( because of exams).
The question is what actually happens when i lift, let's say a tennis ball, up in the air? We say GPE increases, but what actually changes within the atom or what does it means went one object has more energy that another. (other that mass) ?.
Any help will be appreciated.
