Feynman Lectures Quality Video

In summary: The mass of the box and the masses of the light rays add up to the mass of the original body.What's conserved isn't mass or energy separately but mass-energy.Mass and energy are two names for the same thing, and they are separately conserved. The sum of the masses is conserved, and the sum of the energies is conserved. They are two names for the same quantity. In summary, special relativity explains that time and space are the same and can be converted into each other using a proportionality factor of the speed of light, which also affects other physical properties like mass, momentum, and energy. The conversion of mass to energy is a real physical

Here is a dumb thought.
Say, I have a ball in my hand of mass 1 Kg.
I throw it with speed 20m/sec.
Its kinetic energy is 200J. Mass equivalent of this energy is
2.22x10^-15 Kg.
Can we say mass of the ball is increased by 2.22x10^-15 Kg.
In another words, mass of the moving ball is 1+2.22x10^-15Kg, and it will act like a ball of mass 1+2.22x10^-15Kg.
Is this the mass increase we see in special relativity caused by speed?
In such case, it is not a physical increase of mass at all.
A.

oh yes that i was asking all along..! that i want to point..as if how one could explain such conversion...??
