Im having some four-vector definition issues. I have a relativity exam coming up and they quite often ask about 4-vectors.(adsbygoogle = window.adsbygoogle || []).push({});

1) Does this definition sound ok?

'A four-vector is 4 numbers, say X=(X^{0}, X^{1}, X^{2}, X^{3}), used to describe an event in minkowski space. The 'zeroth' is the time component, while the other 3 components are the spatial components of a 3-vector. A four-vector differs from a 3-dimensional vector in that it can undergo a lorentz transformation and remain a four-vector. '

2) How do i show that a vector is actually a four vector?

Do i just show that it remains a valid four vector under a lorentz transformation?

Any help is greatly appreciated

thanks
