Does a photon have mass in motion?

Yes. It is possible to measure the mass of photons Some physicists have found that the mass of photons is constant at around two proton masses.

Do photon have mass?

In the case of photons, there is no evidence of their mass. This does not mean that the photon is massless Just like an object at rest has energy, a photon in motion also has energy. That is, a photon does not have to be at a place to move. It is possible for a photon to have mass but to be at a constant position.

Does a photon have mass in a moving frame?

If you are riding in a train and shine a laser in front of you, you will notice that the train appears to move faster or slower depending on the speed of the train. If you measure the speed of the train from the ground, you will find that it is the same in all frames of reference. However, if you were to ride in the train or look from the train, you will notice that the train appears to be moving faster or slower than the train on the ground. This is

Does a photon have mass while moving?

A photon refers to a particle of light, and it does not have mass. This means that when a photon is moving, it does not experience an increase in mass due to its motion. If it did, the energy required to move that mass would increase, and the photon would have to use more energy to travel the same distance as it did before it began moving. Since that is not the case, it is safe to say that a photon does not have mass while in motion.

Does a photon have mass in a co-moving frame?

Someone moving with a photon would then experience a force towards the photon's origin when this happens. If we describe the photon's origin as the origin of the lab frame, the lab frame would be the co-moving frame for the photon. So no, a photon does not have mass in a co-moving frame because a photon has no rest frame. If you are reading this in a spaceship, you would see the photon's origin as the space ship's origin, and the lab frame would be
