You might be thinking of the word origin.
Zero relative velocity to another object, sure no problem. Zero absolute velocity, not possible as there is no absolute reference to compare to.
A Benchmark Fraction.If Zero is the description of nothing then it would be a useful reference point as everything else can be clearly defined
Zero, if you have a good maintenance program.
For temperatures, zero is an arbitrary reference point, depending on which scale is used. For Celsius, zero is assigned the the temperature at which water freezes. So temperatures which are colder than this temperature will be negative values, and temperatures warmer will be positive values. Fahrenheit uses a different reference point for zero, but similar principles apply.
Because its the zero reference.
The Equator is the zero reference for latitude.The Prime Meridian is the zero reference for longitude.
A zero reference point is a baseline or starting position used for measurement or comparison. In various contexts, such as in engineering or psychology, a zero reference point serves as a point of origin from which other values or measurements are calculated.
depending on machine-x and z zero machine reference points are in the upper right hand corner(away from workpiece) whereas your programmable origin point used for your specific program is completely up to you.

This is not a math number. It looks like a reference code of some sort. "Three zero zero zero dot zero one 4 dot etc"
fan in fan out
reference
This depends entirely upon the direction of movement from the point of reference '0'
