Question: Lorentz transformation involves mass change but mass cannot be transformed into another form?

Answered by Others: The Lorentz transformation is a mathematical tool that helps understand how physical quantities change under relativistic conditions. It does not involve the direct conversion of mass into another form, such as energy or frequency. The Lorentz transformation deals with the relativistic effects of high velocities.

In the context of the Lorentz transformation, the mass of an object does not change. The concept of "relativistic mass" was introduced in the early days of special relativity to describe how an object's mass appears to change with its velocity. However, this concept has fallen out of favor in modern physics, and the more accepted view is that an object's mass is an invariant quantity, meaning it remains the same regardless of its velocity or the reference frame from which it is observed.

The Lorentz transformation does not involve any change in an object's rest mass. It is a mathematical tool used to understand how physical quantities vary between different inertial reference frames and is consistent with the principles of special relativity. Mass (m) remains an invariant quantity in all inertial reference frames, meaning its value remains the same for all observers, regardless of their relative velocities.
