High Speed Energy

[DB]

In the equation:

KE = mc^2 - m0c^2

(can be seen more cleary: http://hyperphysics.phy-astr.gsu.edu/hbase/relativ/releng.html#c1)

What does " m0 " stand for?
And this equation will give me the kinetic and rest mass energy of only a high speed particle???

Im no expert but i think this is how it is!

The m0 stand for the particles rest mass (the mass you can look up in a physics book) and m stand for the relativistic mass

m=m0/(sqrt(1-(v^2/c^2)))

The total energy Etot = EK + m0*c^2 = m*c^2

Did this help?

Ya, thanks just one question what is sqrt?

[danja347]

square root

Ohhh, lol thanks
