The discussion centers on the validity of the proof for E=mc² in the context of accelerating objects within Special Relativity. The proof utilizes the concept of relativistic mass, defined as m = m₀ / √(1 - v²/c²), and derives work done on an object through the integral of force. Participants debate the applicability of Special Relativity to non-inertial frames, with one contributor asserting that the proof remains valid as it operates within an inertial reference frame despite the object's acceleration. The conversation also critiques the term "relativistic mass," advocating for the exclusive use of rest mass in modern physics.
PREREQUISITESPhysicists, students of theoretical physics, and anyone interested in the nuances of Special Relativity and its applications to accelerating objects.

Actually, I found it in an online video: http://www.youtube.com/user/matmania1#p/c/7E2FA65CB78B54B0/14/4cS5qvNJJmA". This video is in Portuguese.starthaus said:Vector calculus is a very powerful tool in obtaining the most general solutions. This is why I mentioned that the solution I provided is much more general than the one you found. Where did you find iit? What book?

My knowledge is somewhat fragmented, since I'm not following a course. I'm learning from what the Internet has to offer. This forum is a very helpful resource.
