Wat does E=MC[size=1]2 mean?





no seirously, i need help on prepositions. Can someone sort of reinforce what it is and give examples?







P.S. nice new forum, just wish it came out last september

e=mc^2
energy=mass X the speed of light squared (^2)

as for an example, an atomic bomb. they are based off the theory that every atom has the energy of its mass times the speed of light squared.

which is a hella lot of energy.

a preposition is a word that shows the relationship of a noun or a pronoun to another word in a sentence

like: we went under the tunnel -under would be the preposition

i have a list from last year lol

about, above, across, after, against, along, amid, among, around, at, atop, before, behind, below, beneath, beside, between, beyond, but(like except), by, concerning, down, during, except, for, from, in, inside, into, like near, of, off, on, onto, out, outside, over, past, regarding, since, through, throughout, to, toward, under, underneath, until, up, upon, with, within, without

i probably misspelled alot because i was looking at my list while i was typing it

i got all of this from a sheet my teacher gave me

thx Mr.Rupe

Why are you learning about the Thoery of Relativity anyway? That's very advanced stuff. Most people can't even get their head around it.

anything a squirrel can do to a tree.

Energy= Mass Conservation.

This means that energy can not be created or destroyed.

And Turaak, I learned about this in the 4th Grade.

Prepesitions are words like under, across, etc.

Please don't joke That's insane.

I've finished school and never did it, I only know about it from looking it up.

Learning about Einstein's theory of relativity in 4th grade? You jest. The only people who learn about relativity in any sort of depth are those who are Physics majors in college.

I digress....

Ummm guys? I was joking about Einstein's equation. Why would someone be learning about prepostions and Einstein in the same grade?


I got a list too, just not understanding it....

I wouldn't say anything...that could go into verbs To put preposition in my own words (not sure if it'll make sense):

A preposition is any word that describes a state of being in comparison to another object. For example, if you are sitting on a stool, you could say you were on (of course) or above the stool. That's where you are in comparison with that.

Uhhh turak no offense but he is right that energy cant be created opr destroyed just transformed

this is called the law of conversation lamo you said you never heard of this and has never learned it i learned it this year and im in 7th now going into 8th *Yeah* anyway you must be like old if you never had learned that they stared teaching that like 3 years ago.....

o also i have a wes why the fudge did you start this now when school has jusy ended...

anyway im very smart so ill prob be hellping ppl in this part alot

Ice mange 22

different courses in england than in the states.

and thats the theory or relativity, not the theory of energy conservation.

as for anything a squirrel can do to a tree, this is full proof. because almost every preposition has a synonymous preposition, so if you cant be about a tree, you can be around.

plus it makes much more sense from latin, because in, on, onto, into, etc are all the same ending.

Wow that made no sence. Punctuation is actually very very useful

I never even said anything to even disagree at.

Energy=mass X the sq of the speed of light

I heard the defeniton on nova.

lol the law of enrgy conservation is the same of the theory of relitivety but if you can tell me how they are differnet that will be interesting cause there the same lol


ice mange 22

ok. here we go.

law of conservation proves einsteins theory of relativity.
that doesnt mean they are the same thing.

theory of relativity is something used for using energy.
law of conservation is something used for finding energy.


and for the record, its not a theory anymore. they proved it about 1-2 years ago in space. so i guess its einsteins law.

Did anyone say they were different Ice Mange? :S

yeah they are lol you just said it the law of enregy conservation proves that ensteins throery of relitiveity is true so showing it is the same lamo

law of conservation= enengy is proven that enrgy can or cant be destroyed
theroy of relitiveity= energy can not be made or destroyed

lol i can argue with you all day if you want to

finding and using us basicly the same thing if you cant find it you can't use it now can you...

ice mange 22

oh yea.

ok if im the cops, im gonna go find a criminal. no wait, i want to go use a criminal.

doesnt make much sense.

for the record, you don't know einstein's theory of relativity.

it states that in any atom the energy it has is equivalent to that of its mass times the speed of light squared. hence the ATOMic bomb.

the law of conservation of energy just states that the atom has energy.

Rofl. Amazing how this topic has turned from me asking about preposotions to becoming a debate-room like argument about energy conservation and relativity....


So=She sat on top of a stool: top is the prepostion, right?

No, on is the preposition. A preposition is a word before a noun that indicates position, hence the name pre-position, before a position somewhere. So it would be He sat on the stool. She was standing behind the post. Anything that shows position.

Lol conservation of energy is different than theory of relitavety in the way the conservation of enetgy does not explain how energy just happens to come out of mass. I mean, sure anyone can understand that energy is never lost, just transformed. But in theory of reletviety, it says precisely how much energy is equal to mass.

Oh and lol, im in 8th grade and i learned about prepositions like in 5th grade..

a preposition describes where something is sort of like its beyond the the house, its above the house
but dont get it confused with an adverb. to tell wheter its an adverb or a preposition just rember
after a preposition its the object
she ran to the house across-across is an adverb
she ran to the house across the field-across is a preposition

hope that helps

prepositions are the relation between two items.

the cow is on the lady

ex.^

that makes no scence at all!!! (E= MC2)

will....... it means is basicly the theroy of relitivity and the law of energy conservation......

ice mange.

they are not the same thing.

google it.

they are not the same thing.

theory of relativity is about how energy is expended.
law of conservation is about how you find the energy.

totally different concepts.

That means Energy (e) is equivalent to the amount of mass multiplied by the speed of light squared.

Don't jump into this without having some grip on relativity. First you should probably learn... lets see... probably Einstein's postulates of relativity.

Here are some:

1. An inertial system is a system in which a free body exhibits no accileration
2. The laws of Physics are the same for every inertial frame of reference.
3. The speed of light has the same value for all observers, independent of the motion of light source or observer.
