if M is the sum of n masses moving at the speed of light ,Energy would be MC^2?

Question

Poincare's E=mc^2 and conjecture?

Answer 1

E=MC*2 means energy is equal to mass accelerated to the velocity of light squared. Therefore, if mass were to reach this velocity it would become infinite energy.

Answer 2

it's pretty close to the kinetic energy equation if that makes it easier for you to put it together. Kenetic Energy=(1/2)mv^2.

the speed of light being c, E=mc^2. it's the amount of energy given off in nuclear fission. when all those uranium atoms lose all those nuetrons, the resulting sum of the masses of those nuetrons gets plugged into E=mc^2 and you have the energy produced by the reaction. light is electromagnetic radiation...the reaction also produces radioation...it moves at the speed of light.

know what im sayin?

Answer 3

Einstein's famous equation is used to convert between mass and energy. You see, the two are interchangeable. It's a little thing known as mass-energy equivalence. A simple example of its use would be in the collison of matter and antimatter such as an electron and a positron which would yield energy in the form of two photons. A more complex example of it use is found in transmutation/nuclear reactions.

Answer 4

no. You're forgetting the oscillation part. There's a part of the energy that depends on the wavelength and has the plank constant in it, if I remeber well.


yep, just checked it: you have an energy of MC² + sum(hv)
h=planks constant .
v=frequency.


you can usually neglect one of the 2 parts of that sum of energies. but it's good not to forget it.
if M big, then e=MC²
if v big, then e=sum(hv)

Answer 5

Yes.

Answer 6

yes, m is mass
