Data Source and Methodology
All calculations are based on the universally recognized physics formula E=mc², formulated by Albert Einstein in 1905. This formula is a cornerstone of modern physics theory and is extensively documented in scientific literature.
The Formula Explained
\( E = mc^2 \)
Where:
- \( E \) is the energy in joules
- \( m \) is the mass in kilograms
- \( c \) is the speed of light (approximately \( 3 \times 10^8 \) meters per second)
Glossary of Variables
- Mass (kg): The amount of matter in a physical body measured in kilograms.
- Energy (Joules): The capacity to do work, calculated from mass using the speed of light.
How It Works: A Step-by-Step Example
For a mass of 1 kg, the energy calculated is \( E = 1 \times (3 \times 10^8)^2 = 9 \times 10^{16} \) joules. This demonstrates the enormous amount of energy contained within a small amount of mass.
