It is a point that is declared to be zero for the purposes of calculations.
An origin or zero point.
The LEAST count would be Zero (0). This is not trivial. There is an established standard for what Zero actually is, as a reference point in Air.BS EN ISO 389 (1997) "Acoustics. Standard reference zero for the calibration of pure tone air conduction audiometers"
When you want to compare something or measure something, in order to make the comparison you have to know and agree where you are starting from. The point at which you are starting is your "reference point"
The pure water freezing point (zero degree) and its boiling point (100 degrees) at atmospheric pressure.
An object with zero kinetic energy is at rest. However, since reference frames are relative, the calculation of kinetic energy is done with reference to an arbitrary point.
An origin or zero point.
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
This depends entirely upon the direction of movement from the point of reference '0'
absolute zero
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.

When the object, whose location is being measured, is at the reference point for measuring displacement.

There is really no such a thing as "absolute potential energy"; potential energy refers to the difference in energy between two points. For purposes of calculation, a convenient reference point is often chosen, and one such reference point is a point at an infinite distance.
Point nought nought two or point zero zero two.
