Lorentz Transformation Rapidity

In summary, the conversation is about the relationship between Rapidity and the relative angle of two frames. It is mentioned that if tanh(Fi) = v/c, it can be concluded that the relative angle, represented by theta, is also equal to tanh(Fi) = v/c. However, there is some confusion about the meaning of the "relative angle." The speaker clarifies that it refers to the angle between the two frames and its connection to rapidity.

Concerning Rapidity, if tanh(Fi) = v/c, can it be concluded in general that the relative angle of two frames in combination with Lorentz Transformation is tan(theta) = tanh(Fi) = v/c, where theta is the relative angle?

What do you mean by the "relative angle"?

Yes,
[itex] \theta_{21} = \theta_{20}-\theta_{10} [/itex].

I meants relative angle of the frames.

That's what you said but what does it mean?

Simply the math connection between rapidity and the angle of two frames, not sure if this is clear?
 

1. What is Lorentz Transformation Rapidity?

Lorentz Transformation Rapidity is a term used in physics to describe the relative motion of objects in special relativity. It is a measure of the rate of change of an object's position in space-time.

2. How is Lorentz Transformation Rapidity calculated?

The formula for calculating Lorentz Transformation Rapidity is arctanh(v/c), where v is the relative velocity between two objects and c is the speed of light.

3. What is the significance of Lorentz Transformation Rapidity?

Lorentz Transformation Rapidity is significant because it is a fundamental concept in special relativity that allows us to understand how time and space are affected by relative motion. It helps us to reconcile the discrepancies between different observers' measurements of the same events.

4. Can Lorentz Transformation Rapidity be negative?

Yes, Lorentz Transformation Rapidity can be negative. This occurs when the relative velocity between two objects is greater than the speed of light. In this case, the rapidity becomes imaginary and represents a hyperbolic angle.

5. How does Lorentz Transformation Rapidity differ from velocity?

Lorentz Transformation Rapidity and velocity are related concepts but are not the same. While velocity measures the rate of change of position, rapidity measures the rate of change of space-time. Additionally, rapidity accounts for the relativistic effects of time dilation and length contraction, while velocity does not.
