# Why is emc2 important?

## Why is emc2 important?

When a particle meets its antiparticle, they annihilate eachother, leaving only a pulse of energy; by the same token, a high-energy photon can suddenly become a particle-antiparticle pair. Altogether, says Hogg, “E = mc2 has been very important in diagnosing and understanding properties of antimatter.”

## How does E mc2 play a role in nuclear fusion?

Fusion occurs when two light atoms bond together, or fuse, to make a heavier one. The total mass of the new atom is less than that of the two that formed it; the “missing” mass is given off as energy, as described by Albert Einstein’s famous E=mc2 equation.

What E mc2 means?

It’s the world’s most famous equation, but what does it really mean? “Energy equals mass times the speed of light squared.” On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.

### What is Einstein’s theory of time?

For example, physicist Albert Einstein’s theory of special relativity proposes that time is an illusion that moves relative to an observer. An observer traveling near the speed of light will experience time, with all its aftereffects (boredom, aging, etc.) much more slowly than an observer at rest.

### What does c stand for in E mc2?

Speed of light
E = Energy. m = Mass. c = Speed of light. from the Latin term celeritas, which means “speed”

How did Einstein prove relativity?

Einstein postulated three ways this theory could be proved. One was by observing the stars during a total solar eclipse. The sun is our closest strong gravitational field. Light traveling from a star through space and passing the sun’s field would be bent, if Einstein’s theory were true.

#### Why was E = mc 2 important to nuclear research?

Still, E=mc 2 had a supporting role in the story of nuclear fission research. Not as the mechanism behind nuclear power, but as a tool: Because energy and mass are equivalent, highly sensitive measurements of the masses of different atomic nuclei gave the researchers important clues about the strength of the nuclear bond.

#### What kind of chemicals are used in nuclear weapons?

Here are the chemicals used in nuclear weapons: Fissile is a material which sustain a nuclear chain reaction to create a powerful energy. Materials that include as fissile are plutonium and uranium Plutonium is a rare chemical element with symbol Pu and atomic number 94 which was named after Pluto, which once used to consider as planet.

How are neutrons used to make nuclear weapons?

In order to make this weapon works, it requires critical mass of the substance and of course a high speed neutrons, so it only takes a few energy to explode. Due to its small amount of energy needed, its power isn’t as big as thermonuclear bomb.

## What are the different types of nuclear weapons?

Fission bomb also known as atom bomb, is a type of nuclear weapon which its atoms are split into a smaller and lighter atoms. In order to make this weapon works, it requires critical mass of the substance and of course a high speed neutrons, so it only takes a few energy to explode.
