In normal mechanics, the kinetic energy is the integral of the momentum with respect to the velocity ( [tex] \int m_0v.dv [/tex]. So, why is the kinetic energy not given by [tex] \int \frac{m_0v}{\sqrt{1 - v^2/c^2}}dv[/tex]?(adsbygoogle = window.adsbygoogle || []).push({});

Sorry it took a few edits to get the maths looking right.
