if E=mc2, then mc2=E, right?

if E=mc2, then mc2=E, right?
I don't get math.

 

[delon]

ya obviously
if a=b
then it's obvious then
b=a

 

[anirtak143]

i think its symmetric property of equality.. yes, ur right...

 

[tnl2k7]

Correct, in maths it doesn't matter which side the equation is on.

[tittat]

4+5=9
9=4+5 (not necessary, it may my be 8+1 or 7+2 etc)

Yes it will work both ways, Energy = Mass x The Speed of Light (300,000 KM/S) Squared there for Mass x Speed of Light Squard = Energry

 

[DeadBattery]

If
a=b
then
b=a

Yes, they are equal.

LOL Math is confusing, I know, but this is one of the things I know for a fact and it doesn't matter what side the equation is on and the answer. However, if there are prenthesis, that's probably where you're getting the confusion.

Don't Question Einstein!

 

[Perfect7]

That's right...
Which part of it don't you get?

 

[LHVWB]

They are definetly equal. Trust me, I do physics.

E=mc², mc²=E, m=E/c², c=√(e/m).

 

[kkenny]

So is
E=MC^2
The same thing as
SQROOT(E/M)=C

:S

 

[LHVWB]

So is
E=MC^2
The same thing as
SQROOT(E/M)=C

:S

It sure is.

You just need to re-arrange the equation. :biggrin:

E=MC^2 - Divide both sides by M.
E/M=C^2 - Take the Square root of both sides.
∴ C=SQROOT(E/M)

i love math! ^^ i hate math tests.. ^^

 

[Dan]

Yep, they are the same.

anirtak143 - Other way around for me! I hate maths but like the tests because if you want you can just sit there and do nothing!

 

[anirtak143]

any more properties? ^^

 

[unique311]

Glad to see that this post got replies...
It was intended to get my account unsuspended.
but at least i learned somthing in the process.

if you are a mod, can you please unsuspend me one more again.

Although Einstein's name is closely linked with the celebrated relation E = mc2 between mass and energy, a critical examination of the more than half dozen "proofs" of this relation that Einstein produced over a span of forty years reveals that all these proofs suffer from mistakes. Einstein introduced unjustified assumptions, committed fatal errors in logic, or adopted low-speed, restrictive approximations. He never succeeded in producing a valid general proof applicable to a realistic system with arbitrarily large internal and external (that is, translational) speeds.I am working on this formula wil correct it when i will get time.............LOL just kidding

 

[kkenny]

aHHH. Advanced math discussion on x10Hosting.
So sad that I can't understand any of this :\

 

[pandaxx]

Math FTW
