Photoelectric Effect And Mass-Energy Energy Equations Must Include Rotational And Vibrational Kinetic Energy Factors As Well As Linear Kinetic Factors. Also Mass-Energy Equation Must Also Include Potential Energy Factors.

Einstein originally proposed in his Special Theory of Relativity that at low speeds E₀= m₀c² + 1/2mv². However, the total energy at low speeds must include the rotationlal and vibrational kinetic enerrgies as well as potential energies. Therefore the proper mass-energy equation at low speeds must be E₀= m₀c² + 1/2m₀v²+ 1/2Iω²+1/2 kx²₀ + Gm₁m₂/r + kQ₁Q₂/r. Originally, Einstein proposed that the ejected electron in the Photoelectric Effect through collisions in the material has lost its original kinetic energy and only the energy from the impacting photon affects the linear kinetic energy of the ejected electron. However, also through collisions in the material the ejected electron all rotational and vibrational kinetic energy is lost and only the energy from the impacting photon is retained by the ejected electron. Therefore, the resulting equation for the
Photoelectric must be hf= (1/2mv² + 1/2Iω²+ 1/2kx²₀ )max +φ to include the rotational and /or vibrational kinetic energies if present in the final Photoelectric Effect equation.
