rest mass การใช้

• :Light is so fast because it has no rest mass.
• Neutrinos oscillate in three flavors and all neutrinos have their rest mass.
• For example, an electron and a positron each have rest mass.
• Photons have zero rest mass, but nonzero relativistic mass.
• :Kinetic energy is the difference between rest mass and relativistic mass.
• For objects with a rest mass this means they are slowing down.
• What we normally think of as mass is rest mass.
• What is the status of the possibility that photons have nonzero rest mass?
• Hence zero rest mass and zero lenght for photons.
• For light with no rest mass, this means the frequency goes down.
• :Except that explanation is wrong because a photon has no rest mass.
• :: : Gravity is a combination of rest mass plus kinetic energy.
• That's any object with a rest mass, not just electrons.
• I assume this is somehow covered under GR since photons have no rest mass?
• :A photon doesn磘 have rest mass, but it still has relativistic mass.
• It is more often accurate because it describes particles and bodies with rest mass.
• It obviously can, since rest mass is not fundamentally different from other energy.
• Though it is a rest mass energy of the constituents of matter is also counted.
• The rest mass can also be neglected.
• I believe all the Lorentz style equations require a rest mass or a rest frame.
