Consider two systems of reference (JI): inertial reference system XYZ, which is fixed and a moving inertial reference system X 'Y'Z', which is moving forward at a speed u 'along the axis OX. Let the point O, O 'at time t 0 = 0 coincide.
l '= modo x 2' - x 1 '= (x 2 - ut) - (x 1 - ut) = x 2 - x 1 = l
In classical (Newtonian) mechanics is assumed that the passage of time does not depend on the relative motion of reference, ie it is the same in all inertial reference modo systems (systems that move uniformly and steadily relative to the other). modo
Let the point M (x ', y', z ') in the system K' moving with velocity v along the axis Ox. During Δ t make it move S 1, and the system K 'moves with respect to the displacement vector K S 2. The total displacement S in the absolute coordinate system:
The essence of the Galilean transformations is that if we have an inertial reference system K, the arbitrary system K 'which is moving modo relative to K straightforward and uniform, will also inertial.
[In the transition to the mechanics of high speeds - relativistic mechanics - Galilean transformation is performed. Valid are Lorentz (Galilean transformation is a limiting case of Lorentz transformations modo with v << c).
Note that the length of the segment AB in the moving SV change its value as the time interval between two events - a different WIS proceeds differently. This finding gives us a theoretical possibility to move in time.] In the body fatter modo font selected vectors. Posted 11.11.11r., Time 11:11 advisable to read:
