The Theory of Relativity (Energy)
We calculate the energy of an object moving at a constant velocity using the special theory of relativity.
| Rest Energy E0 | MJ |
| Relativistic Energy E | MJ |
| Energy Ratio E/E0 | |
| Relative velocity as a fraction of the speed of light v/c | ％ |
The closer the relative velocity is to the speed of light, the greater the object’s energy appears to the observer.
| \(\normalsize Mass\ energy\\\\ \hspace{20px}E_0=m_0 c^2\\ \hspace{20px}E={\large\frac{E_0}{\sqrt{1-{\large\frac{v^2}{c^2}}}}}={\large\frac{m_0c^2}{\sqrt{1-{\large\frac{v^2}{c^2}}}}}\\ \hspace{20px}c=299792.458km/s\\\) |
