Calculate Energy using E=mc²

Formula

The formula to calculate Energy (E) using Einstein's famous equation is:

\[ \text{E} = m \times c^2 \]

Where:

E=mc² Definition

This equation is derived from Einstein’s theory of relativity. This theory, which is now accepted in the scientific community as truth, states that matter and energy are one and the same. Therefore, you can convert mass into pure energy. The equation shows that a small amount of mass can be converted into a large amount of energy, which is the principle behind nuclear reactions.

Example Calculation

Let's consider an example:

Using the formula to calculate the Energy (E):

\[ \text{E} = 1 \times (299,792,458)^2 \approx 8.99 \times 10^{16} \, \text{Joules} \]

This demonstrates that a mass of 1 kg can be converted into approximately \(8.99 \times 10^{16}\) Joules of energy.
