Also question is, is the Z axis vertical?

The coordinate surfaces of the Cartesian coordinates (x, y, z). The z-axis is vertical and the x-axis is highlighted in green.

Furthermore, what does the Z axis represent? z-axis - Computer Definition The third axis, usually representing depth, of a three-dimensional grid, chart, or graph in a Cartesian coordinate system. The z-axis is perpendicular to both the x-axis and y-axis and is used to plot the value of z, the third unknown in mathematics.

Additionally, is Z axis up and down?

These axes are normally taken so that X axis is the longitudinal axis pointing ahead, Z axis is the vertical axis pointing downwards, and the Y axis is the lateral one, pointing in such a way that the frame is right-handed.

What is the Z axis called?

When they are, the z-coordinate is sometimes called the applicate. The words abscissa, ordinate and applicate are sometimes used to refer to coordinate axes rather than the coordinate values.
