Hi, I try to understand why energy can not have a direction. For instance, kinetic energy of a particle could be considered to have the direction of its velocity. Potential energy of a body in a gravitational field also can be considered to have direction (at least in the two-body case). The same for a mass and a spring. Of course, there are cases where forces balance and the potential energy has no associated direction anymore (as with a central body that is being pulled by two springs in opposite directions), still the separate components of potential energy of the central body can be associated with a direction and so can the potential energies of the two bodies at the other sites of the springs. I realize there are some complications and questions, but conceptually I do not see why energy does not have direction.
