Quarlep said:I was looking relative velocities and I saw General case in Relativity part.That part means every direction isn't it.
http://en.wikipedia.org/wiki/Relative_velocity
and in there B is the observer or A is the observer
Thanks

The General Case of Relative Velocities is a concept in physics that deals with the motion of two objects in relation to each other. It involves calculating the velocities of the two objects and their relative velocity, taking into account their direction and speed.
The Special Case of Relative Velocities, also known as the Galilean Transformation, assumes that the two objects are moving in a straight line at constant speeds. The General Case takes into account the possibility of the objects moving in any direction and at varying speeds.
The formula for calculating the General Case of Relative Velocities is V_AB = V_A + V_B, where V_AB is the relative velocity of object A with respect to object B, V_A is the velocity of object A, and V_B is the velocity of object B.
Understanding the General Case of Relative Velocities is important in various fields of science and engineering, such as mechanics, astronomy, and navigation. It allows for accurate predictions and calculations of the movement of objects in relation to each other.
The General Case of Relative Velocities is applied in many real-life situations, such as determining the motion of planets in our solar system, calculating the speed and direction of objects in space missions, and predicting the movement of vehicles in traffic. It is also used in sports, such as calculating the speed and direction of a ball in a game of soccer or tennis.
