Mass and energy equivalence


Since the increase in energy is accompanied by an increase in mass, mass and energy are considered equivalent, expressed by:

$$E=mc^{2}$$


where,

Eā€” energy;
mā€” mass;
cā€” speed of light in a vacuum.

As the velocity approaches the speed of light in a vacuum, the velocity cannot significantly increase, and the mass of the body begins to increase, storing energy as additional mass.

The speed of light in a vacuum is a physical constant with a value of:

$$c=299,792,458 \frac{m}{s}$$
