Wikipedia's 'special relativity' entry gives the following relationship between force, acceleration and velocity:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]

\vec f=\gamma m \vec a + \gamma^3 m \frac {\vec v \cdot \vec a}{c^2}\vec v

[/tex]

but without derivation. Could someone tell me how one arrives at this?

Thanks.
