The Difference Between Electric Potential and Electric Potential Energy

In the case of two charged particles that had the same charge, I wouldn't have to do anything. I just have to let them move apart from each other. Whereas if the particles were instantly charged, I would have to physically pull them apart. So that tells me that it's energetically unfavorable for them to move apart. Now we come to one of the more complicated or at least more confusing things about the electric force which is electric potential. Electric potential in itself is not too hard to understand, it's just hard to understand because we just talked about electric potential energy.
