WebDec 18, 2024 · When the momentum is zero, i.e. in the rest frame of the particle, one gets the $E=m_0c^2$. The relativistic mass is not used in particle physics because of the confusions as in your question. One has to use the four vectors to be consistent with special relativity.

How do we know that a photon is massless? Physics Forums
WebThis relation can also be applied to a photon. In Equation 6.17, E is the total energy of a particle, p is its linear momentum, and m 0 is its rest mass. For a photon, we simply set m 0 = 0 in this equation. This leads to the expression for the momentum p … WebApr 2, 2024 · Rest mass is the mass an object has when you are in its frame of refrence (IE its stationary to you).
