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.DavidCcc said: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
The Galileian system of coordinate is a mathematical framework developed by Galileo Galilei in the 17th century to describe the motion of objects in space. It is a coordinate system used to measure the position, velocity, and acceleration of an object in a three-dimensional space.
The Galileian system of coordinate differs from other coordinate systems, such as the Cartesian system, in that it does not take into account the curvature of space. It assumes that space is flat and that the laws of physics are the same in all inertial reference frames.
The main components of the Galileian system of coordinate are the x, y, and z axes, which form a three-dimensional coordinate system. The origin of the coordinate system is typically located at the center of mass of the system being observed.
The Galileian system of coordinate is significant in modern science as it provided a foundation for the development of classical mechanics and the laws of motion. It also laid the groundwork for the development of modern theories, such as relativity and quantum mechanics.
The Galileian system of coordinate is used in various practical applications, such as navigation, engineering, and physics experiments. It allows for precise measurements of an object's position and motion, which are essential for understanding and predicting its behavior in different situations.
