SIR IS RELATIVISTIC AND REST MASS ARE TWO DIFFERENT MASSES IF YES EXPLAIN WITH THE THEORY OF RELATIVITY AND WHY WE CONSIDER REST MASS ONLY.
Asked by JAIBHARGAVA200 | 3rd Nov, 2014, 08:18: PM
Rest mass is the mass of an object when it is at rest. Relativistic mass of the object is when it is moving with a speed comparable to the speed of light.
According to the theory of relativity, an object’s mass is not constant. It increases with increase in speed. The mass of an object in relativistic terms is given as
Now, when the speed of object is much smaller than c, then we have
Hence, we consider rest mass only for any object. It is only when the object moves with speeds comparable to speed of light, the relativistic mass m is considered.
