What does e. equals m. c. squared actually mean?
E equals mc squared, is an equation derived by the famous physicist Albert Einstein, where E represents units of energy, m represents units of mass, and c squared is the speed of light squared. In another words: "Energy equals mass times the speed of light squared."
The equation — E equal mc2 — means "energy equals mass times the speed of light squared." It shows that energy (E) and mass (m) are interchangeable; they are different forms of the same thing.
