adun Group Title

In relativistic speeds, when calculating the total energy of an particle, I use the formula Eˆ2= mˆ2*cˆ4 + pˆ2*cˆ2. If i use eV as unit for the rest masses m, which unit should I use for the momentum p? eV/c or just plain eV * m/s (only affeciting the value of p I guess) ?

    what is eV/c is it even a unit? do you mean c the speed of light. eV*m/s seems satisfying......

    Well, I actually found out the answer myself. One often use eV/c as unit for relativistic momentum to get a more manageable number. So, you divide the value you get with c so you can write the unit as eV/C instead of eVs/m. Yes, c is the speed of light

    well i guess E=MC^2 MC=E/C where energy of the photon is eV and c the speed of light
