P vs e

Classical Mechanics Level 1

P has a mass of 0 when e does not why is this

Key: e=electron p=photon

P is so unstable that it loses all its mass when it's born P moves at the speed of light and e does not

$9.10938356 × 10^{-31}$ kilograms is the weight of an electron

$10^{-54}$ kilograms is the weight of a photon

As you can see, a photon is quite small compared to protons, neutrons or even electrons, so usually they are taught either to have no mass or ignorable mass

The reason electrons have very low weight, but not as low as photons, is because it moves at speeds close to light , never even equal to, while photons are literally light particles, so they move at the speed of light

So the reason why $\text{P}$ has no mass while $e$ does is because $\text{P}$ moves at the speed of light and $e$ doesn't

Ignore if you hadn't seen this previously :)

Where exactly did you learn that photons do not move at the speed of light?

Oh my God, thanks for pointing out

As you can see, I assumed that it was "protons"

Thanks for clarifying :)
