I was reading a book on the theory of relativity yesterday and it said that by substituting the equation for momentum (p=mv) in to the formula E^2=m^2c^4+p^2c^2..(adsbygoogle = window.adsbygoogle || []).push({});

i will be able to get this E=gamma mc^2..

I was just wondering where they get the "gamma" from? can anyone pls tell me how they get that? Thx

sry, not really good at this.
