| 21. | The invariant mass is the relativistic mass of the system when viewed in the center of momentum frame.
|
| 22. | Moreover, under Lorentz transformations, this relativistic mass is not invariant, while the rest mass is.
|
| 23. | The relativistic mass is always equal to the total energy ( rest energy plus kinetic energy ) divided by.
|
| 24. | Is often called the " relativistic mass " of the object in the given frame of reference.
|
| 25. | :A primary consequence of the relativistic mass is the change in inertia, apparent to outside reference frames.
|
| 26. | The whole idea of relativistic mass is deprecated by experts because it is so easy to misunderstand ."
|
| 27. | :Relativistic mass is a useless concept, because it is synonymous with the totale energy of an object.
|
| 28. | A property called the relativistic mass is defined as the ratio of the momentum of an object to its velocity.
|
| 29. | But of curse photons and other " mass-less " particles has a relativistic mass due to its energy.
|
| 30. | However, for given single frames of reference and for isolated systems, the relativistic mass is also a conserved quantity.
