No, most textbooks mention it though to make it easier for students to initially understand Ep.me121 said:is the mgh one even in the syllabus?
I think the force between two apples you're talking about is refering to Newton's Law of Universal gravitation and not potential energy. For force between 2 masses, since G is a small constant, small masses (like things on Earth) will produce insignificant Fhenry08 said:Gravitational potential energy is generally used in space (where g is never 0, hence EP is -), althoguh they can ask for it on Earth between two apples etc. I wouldn't even use the mgh formula.
