Which relation is shown by Einstein’s equation E = mc²?

Correct answer: Mass & Energy. E = mc² shows that mass and energy are equivalent and can be converted into each other.

Background: Here c is the speed of light.

• Time & Mass: Time is not in the equation.
• Mass only: Mass alone does not give the full relation.
• Light & Heat: Light and heat are not the quantities related.

Did you know? The equation explains the energy released in nuclear reactions.

Memory trick: E = energy, m = mass.
