Answer 2

It would be nice if people who use the not-so-dumbed-down terminology to explain what E and M mean. C is easy to conceptualize. E and M are difficult to grasp. E = energy, true. But what does energy mean? M = mass, but what is mass? If we are to grasp the entire concept then the entire formula must be understood. From what I understand, 1 unit of mass = 1 Polok. And one unit of energy = 1 bright light bulb for a second. So if you use the formula, one polok can power C^2 lightbulbs for a second (or an instant event), or 1 lightbulb for 900,000,000,000 seconds, disproving the myth that it takes alot of poloks to do anything.

People who act smart aren't.

Answer 3

Albert Einstein derived the formula based on his 1905 inquiry into the behavior of objects moving at nearly the speed of light. The famous conclusion he drew from this inquiry is that the mass of a body is actually a measure of its energy content. Conversely, the equation suggests (see below) that all of the energies present in closed systems affect the system's resting mass.


According to the equation, the maximum amount of energy "obtainable" from an object to do active work, is the mass of the object multiplied by the square of the speed of light.

It was actually Max Planck who first pointed out that Einstein's equation implied that bound systems would have a mass less than the sum of their constituents, once the binding energy had been allowed to escape. However, Planck was thinking in terms of chemical reactions, which have binding energies too small for the measurement to be practical. Early experimentors also realized that the very high binding energies of the atomic nuclei should allow calculation of their binding energies from mass differences, however it was not till the discovery of the neutron and its mass in 1932 that this calculation could actually be performed. Very shortly thereafter, the first transmutation reactions (such as 7Li + p → 2 4He ) were able to verify the correctness of Einstein's equation to an accuracy of 1%.

This equation was used in the development of the atomic bomb. By measuring the mass of different atomic nuclei and subtracting from that number the total mass of the protons and neutrons as they would weigh separately, one could obtain an estimate of the binding energy available within an atomic nucleus. This could and was used in estimating the energy released in the nuclear reaction, by comparing the binding energy of the nuclei that enter and exit the reaction.

It is a little known piece of trivia that Einstein originally wrote the equation in the form Δm = L/c² (with an "L", instead of an "E", representing energy, the E being utilised elsewhere in the demonstration to represent energy too).

E=mc2 is one of the most famous equations in physics, even to non-physicists. It states a relationship between energy (E), in whatever form, and mass (m). In this formula, c², the square of the speed of light in a vacuum, is the conversion factor required to formally convert from units of mass to units of energy, i.e. the energy per unit mass. In unit-specific terms, E (joules) = m (kilograms) multiplied by (299792458 m/s)2.

The equation was first published in a slightly different formulation by Albert Einstein in 1905 in one of his famous articles. He derived it as a consequence of the special theory of relativity which he had proposed the same year.

Answer 4

Energy = Mass mulitplied by the speed of light squared.

Nuclear bombs are built on this theory. Electrons are fired into atoms, which then split into other atoms. The split releases the energy. The energy is vast because although the mass of atoms is small the speed of light is 300,000,000 metres per second - and if you square that .. it's a very very big number.. = KABOOM!

Answer 5

What is the Einstein formula E=Mc^2?
======================
E= Mc^2 it is mass of rest of a particle.
It is potential energy of a microparticle (quantum of light).
This potential energy is shown at transition
from one condition in another one (kinetic energy).

Answer 6

E= mc^2

Answer 7

Elephant

Answer 8

E= m c^2
i.e mass*square of velocity of light.
c= 3*10^6 m/sec

Answer 9

E= mc^2, it say neither energy can be created nor be destroyed only it can be transferred/ changed from one form to another .

Answer 10

E = mc squared
