Galilean Coordinates

Galilean coordinates are a way to describe position and motion in classical physics, operating under the assumption that time is absolute and the same everywhere. Imagine a fixed grid that moves along with an object in uniform motion; in this system, the laws of physics look the same regardless of whether you're stationary or moving at a constant speed. This coordinate framework simplifies analyzing motion by allowing measurements of positions and times relative to a fixed, unchanging reference point, aligning with the principles of Newtonian mechanics before Einstein's relativity introduced more complex coordinate systems.
