What does (E) mean in (E=mc^2)?
Answer and explanation
Correct answer: Energy
In the equation \(E=mc^2\), \(E\) represents energy. The equation shows the relationship between mass and energy; \(m\) is mass and \(c\) is the speed of light. Force is usually represented by \(F\), so it is not correct here. Exam tip: learn the meaning of every symbol used in a formula.
