what type of energy is the time component of energy-momentum 4-vector? what are its parts?
The energy in the energy-momentum 4-vector is the kinetic energy. The other three components of the 4-vector are the usual three components of the momentum.
Potential energy is, ultimately, the kinetic energy of the force carrying particles. So *all* energy is ultimately kinetic energy.
You also mentioned "energy is the Time component of ..." , whats that mean? energy is the time component?
