what does the equation (E=mc2) mean to you?

Answer 1

Einstein's greatest contibution to humanity.

Energy = mass times the speed of light.

Answer 2

this the invention of the atomic bomb. the pattern is in a universal pattern: it will happens like that, the motion would be eternal unless an intruder is facing the universal motion instead of the eternal motion. when it is bombarded by the intruder eventually it would succombed to the multiple blows and in self-defense would explode. the energy of the blow-fish. it will expanded and suddenly exploded in the surrounded attack by alien forces. it can be anything which will attack but in the case of E=mc2 it is a neutron bombardment which eventually will split the protons which weight 8 times a neutron and will not expand as much as a neutron which is lighter and as an explosion will expand more.

Answer 3

E=mc2 is energy equals mass times the speed of light squared, mass will always vary, but speed the speed of light is a constant variable, (in other words, it will always be 186,000 miles per second squared or 34,596,000,000)

Answer 4

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 relativistic 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.

This formula proposes that when a body has a mass (measured at rest), it has a certain (very large) amount of energy associated with this mass. This is opposed to the Newtonian mechanics, in which a massive body at rest has no kinetic energy, and may or may not have other (relatively small) amounts of internal stored energy (such as chemical energy or thermal energy), in addition to any potential energy it may have from its position in a field of force. That is why a body's rest mass, in Einstein's theory, is often called the rest energy of the body. The E of the formula can be seen as the total energy of the body, which is proportional to the mass of the body.

Conversely, a single photon travelling in empty space cannot be considered to have an effective mass, m, according to the above equation. The reason is that such a photon cannot be measured in any way to be at "rest" and the formula above applies only to single particles when they are at rest, and also systems at rest (i.e., systems when seen from their center of mass frame). Photons are generally considered to be "massless," (i.e., they have no rest mass or invariant mass) even though they have varying amounts of energy and relativistic mass.

This formula also gives the quantitative relation of the quantity of mass lost from a resting body or a resting system (a system with no net momentum, where invariant mass and relativistic mass are equal), when energy is removed from it, such as in a chemical or a nuclear reaction where heat and light are removed. Then this E could be seen as the energy released or removed, corresponding with a certain amount of relativistic or invariant mass m which is lost, and which corresponds with the removed heat or light. In those cases, the energy released and removed is equal in quantity to the mass lost, times the speed of light squared. Similarly, when energy of any kind is added to a resting body, the increase in the resting mass of the body will be the energy added, divided by the speed of light squared.

Answer 5

Energy = mass times the speed of light squared.

Answer 6

equation to create energy maybe.. though it contradicts the law of conservation of energy but it might be true (that's why it's still a theory) Energy = mass * speed of light squared

Answer 7

it's the special theory of relativity as devised by albert einstein in 1905. energy = mass by the speed of light squared. that's a whole lot of energy...

Answer 8

It means that anything with mass can not reach the speed of light.

Answer 9

It means that you can convert mass into energy. This is what we do in nuclear power plants and this is how the sun gets it's energy.
