What is E=MC2 and why is this important?

Answer 1

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.

Hi:

To answer your question you must go back the last of the ninteenth century when a scientist named Lord Kelvin. What he want to know is why the Sun did not burn out . To understand that. Scientist of his day understood ordinary combustion { meaning things that burn by fuel ,heat and oxygen and he figured if the Sun was made of coal & wood and burn by oxygen burning it would have burn up it fuel in 10,000 year and go out . But the Sun been shinning for millions of years and it an impossibility base on their current theroy

But in lacking any theroy to explain this. Scienists around the world went on a quest to explain this. A lot of theroys were put forth but none them work. Until they discovered radioactive materials and the atomic structure of matter { basically the atoms} around last half of the twentieth century. They found a curious thing about radioactive materials. The mass of the material was alway less than what it was calulated to be. and they emitted high energy paticiples and Gamma Rays. Scienists could not explain this. Until Enstien preposed his theroy that when atoms are split or fuse ( force together) they loose a slight amount of mass and this mass was being turn into energy { a lot of energy} . As was explained by this famous formula E= MC^2. After much experimentions to prove or disproved this. Scienists were able to prove that Enstien was right, and armed with this knowelenge they found that atomic fusion was a million times more efficient at making energy than ordinary combustion so that the Sun will shine for about 10 billion years {10,000*1,000,000= 10,000,000,000 years} thus explaining why the Sun can shine for so long and it lead to both the Atomic Bomb and Nuclear Reactors and our understanding of atomic stuctures and the Stars themselves.

Hope this answer your question

Answer 4

In essence it states that matter and energy are equivalent, but in different forms. C (the speed of light) is such a large number that the equation shows how massive the amount of energy that can be derived from a small amount of matter.

E =MC^2 is the principle by which nuclear bombs and reactors were developed, so for practical application, it has been important to war technology and nuclear power plants for public provision of electricity.

Answer 5

Energy is equal to the mass of an object times the speed of light squared. This deals with the theory of relativity and energy at relativistic speeds, such as the speed of light. It explains how modern physics works, and how time travel may be possible, by reaching relativistic speeds which will in turn slow down the travelers clock.

Answer 6

It means energy = mass x's a constant squared. The constant is the speed of light.

This equation is the theory of relativity, and it means that everything is relative to light, even time. One experiment showed that when two airplanes with super-accurate clocks flew in different directions, the one flying in the direction where the light was going gained some time. According to this theory, if you move with light, you're moving with time, in a way.

Answer 8

Energy = Mass * Constant(2). It is the theory of relativity, the idea that you can propel a mass at the speed of light squared and create energy (more complex then that, but that's what the equation means).

it is used to calculate how much energy would be released in a fission reaction in powerplants or in atomic bonbs by determining the difference in masses of reactants and the products

Answer 10

In a nutshell, it is a relationship between mass and energy which Einstein formulated as part of his theory of relativity.
