really confused and new

man i really didnt understand wt is e=mc². so tell about it.

Mass-energy equivalence. The total energy of a system at rest is proportional to the mass. Otherwise stated: mass is a form of energy. You can convert mass into other forms of energy,and vice-versa. For example, an unstable nucleus could break apart and sent particles out with kinetic energy, but there will be a reduction in the mass of that system.

[scienziato]

If a body has speed comparable to the speed of light mass-energy inter conversion takes place.

Not really. No massive body can have a speed the same as light.

nothing can have speed more than light but if a body has comparable speed than interconversion will take place according to equation.

My mass- 72kg

speed of light- 186000 miles/sec

 

[math] E=72(1.86*10^5)^2[/math]

correct?

 

So we all have a great amount of potential energy, but since i'm made of stable atoms then its almost impossible to ever use that energy? correct?

No massive body can travel at the speed of light. Conversion takes place in nuclear reactions

[scienziato]

but in general relativity mass variation takes place because of conversion of kinetic energy into mass.

When you mix imperial and SI units, kittens die.

Yes, unless you happen to have some antimatter lying around.
