The formulas define the passage between coordinates (R, s ) for an event in the inertial frame PinnedLet’s say it Land (Earth is the third planet in the solar system in terms of distance…)and coordinates (R’, s ) for the same event in the tag MovingLet’s say rocket (Rocket may refer to:)which moves along an axis s with Speed (We distinguish:) Fifth.
It is assumed that the origins time (Time is a concept that humans developed to understand…) Coinciding with the

And determines Clean time (In the theory of relativity, we call the time of a particle the time measured by…)
angle parameter
To simplify the formulas, it is useful to introduce the angular parameter defined by the following formulas:
 also
Using this parameter we can write:
Time dilation
If a rocket clock measures duration Between two events that occur in this rocket, they are therefore separated by a spatial distance the duration measured in the fixed Earth laboratory is
The duration measured by an external standard is always greater than the own duration.
Lorentz transformations
Which gives in matrix form (easier to visualize):
Using hyperbolic functions forcorner (In geometry, the general concept of angle is divided into several concepts…) Î¸we obtain expressions similar to the formulas for changing the coordinate axes by rotating the plane:

A projectile is fired at the missile quickly Th Relative to the reference of this missile, in the direction of movement. Speed Th of shell relative to Earth
Using angle parameters
We have the additional law
Length contraction

The length measured on the ground is smaller than the length of the rocket.

Doppler effect
It is the frequency that is received on the ground, The frequency emitted by the source, The angle that the photon makes with the axis bull In reference to this source, Angle with axis bull In terrestrial landmarks, The speed of the source relative to the ground and Radial velocity, we have
