If you can imagine that everything in physical reality is basically energy formulated into physical forms. In physical reality we have matter in its various shapes and forms. Most commonly it is solid, liquid or gas, but sometime under extreme conditions the atoms of any matter lose their subatomic bonding structure and break down into free electron, neutron and protons. Such cloud of subatomic particles is called plasma, and hence the plasmodia soup out of which all other elements like hydrogen, oxygen and carbon, were eventually formed.

Now all things are made of energy then they can also be converted back into energy and this is the central point in the mass-energy conversion equation E = mc2. According to the law of conservation of energy – the entire energy of a system stay the same as energy can neither be created not it can ever be destroyed; energy just changes forms.

If a certain material object has a certain amount of energy encapsulated into its material form, say a chair for example, then this energy is in the form of construction of all its atoms – an atom is only stable because there are electrons constantly revolving round it nucleus.

When we mover things in space we add a little energy into them, and that addition is compensated by a slowing down of every thing inside an atom. If we move something very fast than change delay inside an atom, or time dilation in that object by an outside observer will become more noticeable. There is certain limit, the speed of light, beyond which the internal subatomic kinetic energy of an object come to zero, and at this point atomic structure melts into electromagnetic radiation. When an incident ray of light is brought to halt by directing it on a light absorbent surface light turns into heat that then is added to the internal energy of atoms and molecules.

The normal procedure is either burning,fission or fussion reaction. There exist a stable mass for each substance when the above events occur there is by product ,The total mass of by-product to that of to reacted object will be less this difference in mass will become energy.
The interaction of matter with its anti matter will cause pure energy and no by_product, eg:- if electron combine with a positron then entire mass will be converted to energy.
In both the cases the energy is proportional to mass lost
E=m.(c^2)

Here is one way:
uranium atoms are split into thorium and alpha particles. This converts some of the mass into 4.678 Mev of energy.

There are many other ways to convert mass into energy.

Um, you can get mechanical energy by friction (think lighting a match.)

But another good way to think about it is potential energy. If you have a bowling ball on top of the Sears tower, there is a shitload of potential energy in that sucker (PE = Mass*gravity*height).

Kinetic energy also increases with weight but the mass needs to be in motion.
KE = 0.5*mass*(velocity^2)

e=mc^2
e=energy
m=mass defect
c^2= the speed of light (3.0e8 m/s) squared
the only equation you'll need for the small portion of high school physics that deals with mass-energy conversions.

anti-matter reaction. this is when matter meets anti matter and they reactan turning matter (and the anti-matter) into pure energy - this is einstein's e=mc². even in nucleur reactions not all the mass is converted into energy but in this anti matter reaction it is possible.

if an object travels at the speed of light ^2it posseses energy.

what mass? if it is wood you could light the wood on fire, the wood decreases in mass, creates heat, the heat could be used to warm water, to create steam, to power and old locomotive.....

matter and energy are the same. matter is simply trapped energy.
