Velocity Addition: Angled Motion Explained

[Myslius]

TL;DR

How would you derive a formula for relativistic velocity addition where u and v aren’t parallel? I’m looking for a formula where theres an angle involved

Any ideas?

Where have you looked already?

 

[Myslius]

This formula seems incomplete, there's no angle

Do you understand how that formula is derived?

Yes, so you might want to check other sources. It shouldn't be hard to find a source online that has the more general formula.

 

[Myslius]

It takes into account that only one coordinate x is transformed as far as i understand, i want to calculate relative velocities for any angle, let's say 30 degrees angle

 

[Myslius]

Well if you have a source or know a formula already that would be great

So if you can see how it transforms $\Delta x$ then can you do the same for $\Delta y$?

For something that can be found this easily with an online search, it would be better for you to find or derive it yourself. If you have a question about what you find, you can start a new thread to ask it.
