What does m mean in E = mc²?

Answer and explanation

Correct answer: Mass

The correct answer is D, mass. In Einstein’s equation E = mc², m represents mass, E represents energy, and c represents the speed of light in a vacuum. The equation connects the amount of matter in an object with an equivalent amount of energy. Speed cannot be the meaning of m because the relevant speed is represented by c; energy is represented by E, and light is not the quantity denoted by m. Thus option D is the only scientifically appropriate answer. Careful reading of notation is important here: a symbol is defined by the equation and its scientific convention, not simply by guessing from the first letter of an unrelated word. Understanding these symbols makes the equation more meaningful.
