what does Einstein's equation(E=MC2) means?

Question

what is the relation between the speed and mass

Answer 1

It appears that Bryan has put his words together very well. To verify it would be a small challenge but as the saying goes you must challenge the material that you have that is used to make the verification. A round circle is not round. Give ten points to the man.

Answer 2

In This equation:
"E" stands for energy
"m" stands for mass
"c" stands for the speed of light

The reason this equation is so important is that until that time there were two parts to the First Law of Thermodymanics. these were the consevatiion of mass and the consevation of energy

This equation linked the two parts together. It said that mass could be destroyed, but when it is destroyed it produces a tremendous amount of energy. Theoritically it should be possible to take that same energy and transform it back into mass, but practically that is not possible.

We have all heard of the Hydrogen Bomb. In simple terms here is how it works. Deuterium is an isotope of hydrogen. Its atomic weight is slightly over 2. (lets say 2.1) In the bomb, two deuterium isotopes are rammed together. As they collide, they "Weld" together and form one Helium atom. Its atomic weight is exactly 4. The original pair of atoms had acombined mass of 4.2 Helium has a mass of 4. what happened to the 0.2 of excess mass. It becomes energy at a rate of "the speed of light" squared. this is a huge amount of energy. In the sun this type of atomic reaction is going on billions of times each second. That is the main reason that the sun is so hot

I hope this answers your question

All the best

Answer 3

It basically states that any matter has a huge amount of energy associated with it. For example, a gram (always use metric) would have 1*(299793458^2) joules. That's a lot, more than any atomic weapon. In fact, an atomic weapon operates on this principle. That is, somehow, in a atomic reaction some of the mass is destroyed, it's gone. Not so in any other reaction, such as combustion, the "lost mass" is converted into gases. The energy released comes from breaking some chemical bonds, not the actual loss of mass. If that were true, fires would be very very hot, since they lose more than one gram of mass.

Answer 4

Because people who read too much fall into habits of thinking, duh. He means that if you don't put your thoughts into action then you're going to think too much on what could have been, or something along those lines. He just means that if we sat around pondering all day what to do, how to do, when should do then we aren't gonna get bloody anywhere! That's why he wasn't a politician!

Answer 5

The equation yields the rest energy of a particle. Under the Lorentz transformation particles have different total energies in different inertial frames. This equation leads to the rest energy of the particle in it's stationary reference frame.

Answer 6

THere is not relation between speed and mass.

Mass is always the same

Answer 7

It describes the energy equivalent of matter and the mass equivalent of energy.

There is no understood way in which all matter can be converted into energy.

Answer 8

It means that energy and matter are two different forms of the same thing and can be transformed from one for to the other.

Answer 9

energy = mass * (speed of light squared)

Answer 10

I think it has something about driving very, very fast.
