A common frame of reference when describing motion is the observer's point of view or a fixed point in the environment that is used as a reference to describe the motion of an object. This helps to establish direction, speed, and location of the object in relation to the observer or the fixed reference point.
Earth potential is considered as zero potential because it serves as a reference point for electrical systems. By defining earth as zero potential, it allows for easier analysis and measurement of voltages in circuits. This simplifies the design and operation of electrical systems.
Earth is considered to have zero electrical potential because it serves as a common reference point for measuring the electric potential of other objects or points in a system. Since Earth is so large and its charge is effectively neutralized by the presence of both positive and negative charges, it is commonly chosen as the reference point for zero potential in electrical circuits and calculations.
The two reference temperatures on the Celsius scale are the freezing point of water at 0 degrees Celsius and the boiling point of water at 100 degrees Celsius.
A frame of reference in physics, may refer to a coordinate system or set of axes
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.
