Galileitransformaatioihin

Galileitransformaatioihin refers to a set of transformations in classical mechanics that describe how the laws of physics appear in different inertial frames of reference. These transformations were developed by Galileo Galilei and later formalized by Albert Einstein in his theory of special relativity. The Galilean transformations are applicable when the relative velocity between two frames is much less than the speed of light.

The basic Galilean transformation equations relate the coordinates and time in one inertial frame (S') to another inertial frame (S) moving with a constant velocity v along the x-axis. The transformations are as follows:

x' = x - vt

y' = y

z' = z

t' = t

These equations indicate that the spatial coordinates (x, y, z) in the moving frame (S') are related to the spatial coordinates in the stationary frame (S) by subtracting the product of the relative velocity and time. The time coordinate remains unchanged, reflecting the assumption that time is absolute and the same in all inertial frames.

The Galilean transformations have several important implications. They show that the laws of physics are the same in all inertial frames, a principle known as the relativity of uniform motion. However, they also reveal that the speed of light is not constant in different inertial frames, which is a key difference from Einstein's theory of special relativity. The Galilean transformations are thus a good approximation for velocities much less than the speed of light but break down at higher velocities.
