Where the first equation describes relativistic energy, the second relativistic mass, the third charge invariance, and fourth spin invariance.

Instead, the energy provided to it is converted to mass, and its relativistic mass increases, in what is known as mass dilation.
43.
This is why physicists usually reserve the useful short word " mass " to mean rest mass, or invariant mass, and not relativistic mass.
44.
The relativistic mass corresponds to the energy, so conservation of energy automatically means that relativistic mass is conserved for any given observer and inertial frame.

:For completeness, the concept of relativistic mass that you seem to be referring to is obsolete and no longer commonly used in modern physics.
47.
When you move an object you give it kinetic energy, that results in it having a greater mass ( we call it relativistic mass ).
48.
If the object is moving slowly, the relativistic mass is nearly equal to the rest mass and both are nearly equal to the usual Newtonian mass.
49.
That's true for relativistic mass, not true for invariant mass .-- talk ) 18 : 17, 22 November 2010 ( UTC)

It is a common misconception to think that space contraction and relativistic mass makes it possible for a fast moving object to turn into a black hole.
