This tells you how to calculate engery.

E=MC2 describes the potential energy in all matter. Since C is the speed of light, and C squared is a HUGE number, there is lots of potential energy stored in all matter.

There isn't really a practical application unless you're building an atom bomb or a time machine.

it means
that when a particle travels with a speed comparable to that of light

its mass changes to energy

its aplication exists in relativity
where the mass decreases and is transformed to energy

aight
here goes a borin answer
e = enegry (potential energy stored in a mater)
m = mass of the matter
c = veloctiy (not speed) of light

now, get it, the energy is stored IN the the matter
( ie the energy that can b derived from nuclear fission,
breakin the nucleus releases a lotta energy, thats how atom bomb works)

the amt of energy ( in joules) can be calculated by multiplyin the mass of the matter wid the velocity of light times two.
the vel of light , as we all know, is 3000000 km per sec.

this is totally practical.
this is actually how hydrogen bomb, atom bomb and the nuclear reacters work.

p.s. c( vel of light) aka Einstein's Constant

Energy(=E) and mass(=m) are equivalent. You can express that with E=mc2 with c = the velocity of light. It comes from the theory of relativity of Albert Einstein.

When a uranium nucleus is attacked by a neutron they first merge and then they split into two peaces. About 1% of the total mass dissapeared and in return you get a equivalent amount of energy. This is fission.
Also with fusion (from hydrogene to helium for instance) it is applicable.

e=mc2 indicates that energy and mass are interconvertable.a little change in mass can create energy like that in nuclear bombs and also a little change in energy can create mass like the mass of the stars from the dark energy of the universe.there is a hint in mahabharata where dharmaraja asked yudhistira that what travels faster then light and he answered it is 'mann' this means our anscestors knew the fact that light is only the physical thing which travels fastest.

It is the only ewuation which gives any relation between energy and mass.
