Many basic texts on relativity refer to the mass variation equation:
m= gamma mo
[gamma = Lorentz factor, mo= invariant(rest) mass]
It seems that there are some good reasons including,for example, problems with definitions of mass, why the equation is not favoured by a majority of physicists the alternative equation involving E squared, p squared and so on being preferred. What I am trying to find out is the following:
How widely is the equation (m= gamma mo) still favoured and is it considered to be a useful equation? To me it seems to be a useful and simple equation for calculating the kinetic energy of a relativistic particle.
Thank you.
