### Matter-energy equivalence
The kinetic energy of an object in an inertial frame of reference relative to another is related to its velocity and its mass.
$$E_k=\frac{mc^2}{\sqrt{1-\frac{v^2}{c^2}}}$$
The total energy of an object in an inertial frame of reference relative to another is related to its velocity and its mass.
$$
E_t=\frac{mc^2}{\sqrt{1-\frac{v^2}{c^2}}} \\
E_k=E_t-E_\text{rest}
$$
At rest, the energy of an object is related to its mass.
$$E_\text{rest}=mc^2$$
