E=mc²

Mass–energy equivalence

E=mc²

Albert Einstein's famous equation E=mc² establishes the relationship between mass and energy, showing that they are interchangeable.

Example

If a particle with a mass of 1 kg is converted entirely into energy, it would release 9 x 10^16 joules of energy.

Remember this

This equation highlights the profound connection between mass and energy, fundamental to understanding both physics and cosmology.
