1I THINK MASS VARIES AS
m = m0√ ( 1-v2c2)
where m0 is the rest mass of the particle.
v = velocity of that body, c = velocity of light.
while i was having fun with physics at wikipedia'website a doubt came in mind ,as mentioned her::::::does the mass of ne body or particle vary while it is moving wid large velocity?????if YES wht r the conditions?????why this is happening????????does the body need to be a microparticle to satisfy this condition?????????if NO try explaining this :::
"in the Large Hadron Collider (LHC) (pictured) protons, accelerated to the energy of 8 TeV, move at 99.999999% of light speed and become 7,000 times (on grounds of mathematical calculations) heavier than at rest"
confusion makes us richer in knowledge...............:):):D:P

29According to Einstein' famous eqn..
E = Mc2...
mass is a new form of energy..wen we apply some force on a particle..it's velocity will increase upto a certain extent..then afterwards the enrgy provided gets converted into mass and the mass of the particle increases......
1why this is happening????????does the body need to be a microparticle to satisfy this condition?????????
29well i dont think the body needs to be microscopic...if we can provide enough energy to a macroscopic body then in that case mass may increase..though i am not sure abt it....
49conditions are mass must move
the mass change is not notable if the velocity is not comparable to speed of light!![1][1][1]
49now i have a doubt...
let a mass m moving with a velocity v
has energy 1/2mv2...but einstein tells its mv2...explain...[3][3][3]
13Actually Sanchit, thts a gr8 debatable topic u've raised....n v can't approach it without being in-depth in relativity theory.
See this if u want (even Tesla challenged Einstein's theory)-

Waise, this Qn had also come into my mind last yr n i even searched...
Firstly, it all depends on whether u talk in terms of rest mass, relativistic mass or an invariant.
Secondly, The accelerating body won't measure its mass as changed. It is an outsider who is (at rest wrt body) who would think tht the body's mass has changed, 'coz the work required/force required to further "push" the body increases manifolds.
This increase can be credited either to momentum, or to mass...Some ppl also attribute it to time dilation rather than mass dilation or an increase in internal resistance...or a ghapla of reference frames!
The conclusion is tht v need a lot of research n understanding n time to clear out all this...jo abhi nahi hai apane paas [3]...so baad mein dekhenge...!!
(I've got a huge lot of things jo mujhe clear out karni hain in future :P)
Nyways, a good discussion in this regard... http://www.physicsforums.com/showthread.php?t=33552&page=2
So, very mind-boggling....Phew!
1so u mean the change of mass is hypothetical....nd we need more research on it...............yaar ye toh galat ques aa gaya dimaag mein samajh hi nahi aa raha.........................:P:D:P:D
1@ subhomoy,
the 2 Es are different. Einstein's E represents the amount of energy in mass. so it is independent of motion. basically, anything with mass is energy....the other E is essentially the kinetic energy of motion when v is very small relative to c
Also Einstein's E cannot represent K.E. as mass cannot move at speed of light :)
