Galileo's Principle of Relativity

Form #1: The laws of physics hold in all unaccelerated reference frames*.

Form #2: No experiment can measure the speed or direction of a solitary object; the motion of an object cannot be measured in comparison only to space itself.

Form #3: Speed and direction are relations, not properties; the motion of one object is not meaningful without comparison to another object.

p align="center">Form #4:
GPR

*A reference frame is a perspective determined by the observer's velocity not by the observer's position.

The Laws Hold in every Uniform Reference Frame,

A Reference Frame is a Coordinate System. . .

GPR, Form #5
Commonly known as

Newton's First Law of Motion:

Unless acted on by a net external force, an object at rest stays at rest and an object in motion stays in motion at the same speed and in the same direction.
