Relativity to simultaneity and twin paradox

The velocity addition topic into the special theory of relativity is interesting one, where in addition to the two observers (two frames) included; (1) an idea of the additional object that might be a ball, a rocket or any thing ...

In classical mechanics, the mass of a moving particle is independent of its velocity. But in special theory of relativity one can see that mass is also relative. In the special theory of relativity, length, time, velocity and mass is ...

In classical mechanics, mass of a particle is considered to be a constant quantity and independent of its velocity. However in relativistic mechanics the length, time and mass also depends on the relative velocity.Suppose two similar balls B1 and B2 ...

In this video lecture I have discussed about the Length Contraction.  To understand it the basic information about the two transformations (Galilean and Lorentz) are important. It is based on the basic concept of Frame of References, here two frames ...

 The Einstein in 1905 introduce the concept of Special Theory of Relativity. In our daily life we see the effects of the relative motion, for an example if suppose there are two cars one is BLACK and the other RED ...

In this video lecture I have discussed about the time dilation, which comes under the Special theory of Relativity Unit. To understand this concept the basics like frame of reference, Observer and events idea should be clearer. Here both S ...

In this video lecture some basics of the Atomic Dipole Moment are discussed. How one atom can be equivalent to the tiny bar magnet? and when an atom is placed in a uniform magnetic field the how to find out ...
