Rather than focus on the standing O, Achor obsessed over the one guy. I needed to hear that, and maybe you need to hear it too. See, our brains evolved to pick out potential threats. We live in a world very unlike the one for which our brains are suited, and so we end up with a lot of weird anxiety and trauma reactions to things because 10, years of evolution has us wired to take an anonymous comment on a post as a sign of danger, like a rival preparing to challenge our position in the tribe.
I can bring a little reason to it. I can remind myself of the people who were kind and supportive, and I can give myself the space to experience that positivity. And the more I notice these kinds of things, the sooner I notice them the next time they happen.
On the other hand, instead of considering PE as a positive quantity of energy "invested" in our position energy we've already "spent" if we were moving away from the massive object, which we could gain by moving closer , we can instead consider it a negative quantity of energy we "owe" because of our position energy we've gained "for free" if we moved closer to the object from infinity, which we would have to "spend" to escape to infinity again.
All the calculations of energy differences work out the same anyway. But now our PE relative to an object goes to zero as we get very very far away from the object. The fact that the gravitational potential energy as with all potential energies of attarctive forces are negative is based on the fact that we want to assume that when the particles are at infinity with respect to each other and at rest the system have zero total energy.
Imagine if this was not the case and a system of two particles at infinite separation at rest would be taken to have a net energy then there would arise some confusion as to energy associated with the rest mass.
From where then would this extra energy come? The big mistake is in assigning the P. This is clearly wrong--P. The P. I will express this as an integral after I brush up my calculus. Viz, P.

Why is gravitational potential energy negative, and what does that mean? Ask Question. Asked 9 years, 3 months ago. Active 2 years, 9 months ago. Viewed 57k times. If potential energy really meant what I thought it did, then it would always have to be non-negative So what does "negative potential energy" mean!? Shouldn't this mean all particles increase to infinite KE before a collision?
Do they both represent the same "form" of energy? However, the two equations give completely different answers! What gives!? Can anyone help clear up my confusion? But as we said what the gravitational potential energy wants to do is the opposite! The gravitational potential energy is negative because us trying to do the opposite of what gravity wants needs positive energy. There is also the deeper reason why it is negative, due to integration, but that's what you need to know.
