2. Misunderstanding About The Equation.... E = mc2
E = mc2 is a famous equation that has been established by the great scientist Dr Einstein, and it is related to the special theory of relativity.
The special theory of relativity is established on two main postulates, as follows:
1. Velocity of any physical particle or object always remains less than the light-velocity.
2. The velocity of light, i.e. photons is constant. It means that the velocity of source of light never affects its light-velocity.
And according to the second postulate in the equation E = mc2, E denotes total energy, m denotes mass of object, and c is the light-velocity that is accepted as constant.
Generally, all, who have not studied physics or special theory of relativity know that (1) mass and energy are interchangeable, (2) energy of object or particle is equivalent to its mass multiplied by the speed of light squared. In reality 'm' in the equation E = mc2, does not denote restmass, but it denotes the mass of particle or object with the velocity 'v' and therefore m is a variable for the same object according to its velocity. As velocity increases, m increases and therefore E increases. If the velocity of a particle becomes approximately equal to light-velocity, m tends to be infinite. It means that the energy of a substance or particle is not
constant.
In the equation E = mc2, mc2 denotes the sum of rest energy mc2, and its Kinetic energy, and it is denoted as E = mc2 = mc2+ K.E* Here m c2 is constant for the same
