Study route
30.1 Reciprocity postulates
- The laws of physics are the same in all inertial systems, and the speed of light in the vacuum is the same for all the inertial observers, regardless of the movement of the source.
30.2 Relativist effects
- Time itself is measured by clocks moving with the process and length in the object's rest system. In another system, intervals are linked by Lorenz's factor.
30.3. Energy and pulse
- The power of the rest is connected to the mass, and the full energy includes movement. For a massless photon, the energy and impulse remain unzero.
