HEP: Energy Only in Kinetic or Potential Forms?

  1. Nov 25, 2012 #1
    I read recently that all energy is either kinetic or potential.

    In high energy physics, it is easy to understand the kinetic bit, but potential energy eludes me. What are some examples of potential energy at the high energy physics/elementary particle level?

    Also, if strings exist, how is kinetic and potential energy related to their vibrations/rotations (in layman terms please :)) or is this energy duality not applicable at this level?

    You could consider the binding energy in hadrons as potential energy.
    Mass as type of energy is missing in the list.

    Vibrations/rotations would give different masses and other properties of the particles, energy is like in conventional particle physics.
