Discussion Overview

The discussion revolves around the concept of the Galilean system of coordinates, with participants exploring its definition and implications in the context of physics, particularly in relation to motion and forces.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant seeks clarification on the Galilean system of coordinates, referencing a chapter by Einstein.
  • Another participant questions the terminology, suggesting that "Galilean relativity" is more accurate and notes that the Galilean transformation is the simplest way to relate different observers' viewpoints.
  • A different viewpoint states that a Galilean system of coordinates is defined by the applicability of Newton's three laws of motion in their standard form.
  • Another participant reiterates the initial query and adds that in a Galilean coordinate system, objects maintain their speed and direction unless acted upon by an external force.

Areas of Agreement / Disagreement

Participants express differing views on the terminology and definitions related to the Galilean system of coordinates, indicating that there is no consensus on the precise terminology or conceptual understanding.

Contextual Notes

There is ambiguity regarding the definitions and terminology used, particularly the distinction between "Galilean system of coordinates" and "Galilean relativity." Additionally, the application of Newton's laws in this context may depend on specific assumptions about the reference frames involved.

What is Galileian system of coordinate?
I have read the chapter about it by einstein but still can't understand it.
Can anyone kindly explain it to me?
thanks

Are you referring to Galilean relativity? To my knowledge, no coordinate system is called Galilean, but the simplest transformation from one observer's viewpoint to another is called the Galilean transformation.

A Galilean system of coordinates in one in which Newton's 3 laws of motion hold in "standard" form.

atyy summed it up, but another way of looking at it is that with respect to a Galilean coordinate system, or inertial reference frame, objects don't change speed or direction without an applied force.
