What is E, what is M, What is C, squared?????????

Question

Is e=Mc squared calculas?

Answer 1

Got no idea.

Answer 2

E = mc2

E = energy (measured in joules)
m = mass (measured in kilograms)
c = the speed of light (186,000 miles per second, or 3 ´ 108 ms-1)

It's not calculas, it's physics. This is Albert Einstein's theory of relativity.

I hope this helps you to answer your question. The source link has more of a detailed explanation.

Answer 3

It's used to describe energy in science. I don't think it's calculus as much as a scientific equation.

E= Energy
M= mass
C= constant (I think)

Edit:
Looks like I was wrong on what c stands for. But listen to the other people who are talking about it being Einstein's theory. They're right.

Answer 4

It's physics. It's Einstein's theory of relativity, though I don't recall what it does at the moment.

The "e" represents the energy.
"M" is the mass of the object
"c" is the speed of light in a vacuum (roughly 300,000 km/s - or 186,000 miles/second), and then the "squared" is the mass times the speed of light squared. That gives you the energy.

Answer 5

This is how I was taught it:


E = the energy equivalent to the mass (in joules),
m = mass (in kilograms), and
c = the speed of light in a vacuum (in metres per second). (celeritas)

Thanks to NOVA for finding celeritas for me

It's Einstein's theory of how matter and energy are different forms of the same thing

Here's a good explaination:

Matter can be turned into energy, and energy into matter.

For example, consider a simple hydrogen atom, basically composed of a single proton. This subatomic particle has a mass of

0.000 000 000 000 000 000 000 000 001 672 kg

This is a tiny mass indeed. But in everyday quantities of matter there are a lot of atoms! For instance, in one kilogram of pure water, the mass of hydrogen atoms amounts to just slightly more than 111 grams, or 0.111 kg.

Einstein's formula tells us the amount of energy this mass would be equivalent to, if it were all suddenly turned into energy. It says that to find the energy, you multiply the mass by the square of the speed of light, this number being 300,000,000 meters per second (a very large number):
= 0.111 x 300,000,000 x 300,000,000
= 10,000,000,000,000,000 Joules

A Joule is not a large unit of energy ... one Joule is about the energy released when you drop a textbook to the floor. But the amount of energy in 30 grams of hydrogen atoms is equivalent to burning hundreds of thousands of gallons of gasoline!

(sorry I'm bad with names) And yes the person who said it was physics not calculus is correct (-applause-) thanks for remembering to mention this (and I do apologize that I forgot your name, so sorry).

Answer 6

E= energy
M= mass
C= speed of light

Albert Einstein's famous equation from his theory of relativity. Used in physics not calculus.

Answer 7

Einsteins theory of relativity-
Energy equals mass times the speed of light squared.

I think that it really means if you get too involved with this stuff you will have REALLY BAD HAIR !!

Answer 8

ALL of those people are wrong about one thing. M is equal to the "missing" mass of the object, not the mass. Everything else they said was right.

Answer 9

E stands for ENERGY
M stands for MASS
C stands for CONSTANT (the speed of light)
the speed of light is 670,616,629.2 miles per hour
so
energy is equal to mass times the speed of light squared

Answer 10

E=MC2 is not calculus, it is physics

And not using spell check = prideful ignorance

Answer 11

Its a secret, and if I told you, Id have to silence you.
