No, E = mc² is not the theory of relativity. It is an equation derived from Albert Einstein's theory of special relativity, describing the relationship between energy (E), mass (m), and the speed of light (c squared). Special relativity, published in 1905, and general relativity, published in 1915, are extensive theories explaining space, time, and gravity.

FAQs & Answers

  1. What is the difference between special and general relativity? Special relativity deals with objects moving at constant speeds, primarily focusing on time and space, while general relativity incorporates acceleration and gravity.
  2. How did Einstein derive E=mc²? E=mc² emerges from the principles of special relativity, showing how mass and energy are interchangeable.
  3. Why is E=mc² important in physics? It revolutionizes our understanding of energy-mass equivalence, influencing various fields such as nuclear physics and cosmology.
  4. What are some applications of E=mc²? E=mc² is fundamental in nuclear reactions, explaining both energy release in nuclear fission and fusion.
