can someone explain mass-energy equivalence by considering this example:-
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....

it looks as a dumb thought then and mass-energy equivalence appears fanatical..!!

@rajathsbhat ,@experimentX,@UnkleRhaukus ,@TuringTest      ..can u help me on this..!!

Um, yeah~ The mass is ' increased' a little

anonymous · Answer

Umm yeah. I think you can see it like this:
To accelerate the ball, you expend some energy, right? So you're transferring some your energy into the ball. I think it is also absolutely correct to think that you are losing the mass that the ball is gaining.
p.s. note how infinitesimally small this 'mass' is.
