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…

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 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…

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,…
