Okay, I hate you bringing this up, because it's physics related, and physics is the spawn of satan.
All the concepts like this are interrelated, so I'll use a concept to see if it helps you understand/remember how this works better.
I'll just focus on kinetic energy, since potential and kinetic energies are opposites, you can deduce that when kinetic energy increases, potential energy decreases, etc (you got that?). This is how to relate kinetic energy to everything in chemistry: as temperature increases so does your average kinetic energy. There, that's it, simple.
So lets relate temperature to exothermic/endothermic and bonds. When you boil water, or melt ice, what two things are generally occuring? You're breaking bonds and you're increasing the temperature; just from my mention of temperature, you should automatically go AHAH, an increase in temperature means an increase in kinetic energy! When you break bonds, you put energy in to force those bonds to break, energy in is endothermic, right? Putting heat in (to raise the temperature) is endothermic, right? So endothermic processes increase kinetic energy (while PE is obviously decreasing).
Going the opposite way, as you freeze something, bonds are being formed and temperature is decreasing (exothermic, losing heat), so considering temp decreases, so is our kinetic energy decreasing (not much movement going on in that block of ice).
Well, hope that deconfuses you.
Cheers
