How to pronounce “x direction” in English

We have momentum in the x direction, the y direction, the z direction.

So there's pressure pushing in the x direction, the y direction, the z direction.

So if you imagine writing those vectors as components in the x direction, y direction, z direction, then each component obeys F in the x direction

So if an electron is traveling in the y direction and the magnetic fields are in the x direction, this force, called the Lorentz force, pushes it in the z direction.

Secretly, it's talking about three different quantities, the x direction, y direction, z direction.
