Formula: Relativistic energy-momentum relation

Energy

Unit
Relativistic total energy of a body, which is also valid at high velocities.

Rest energy

Unit
Rest energy is the energy of the body in its resting frame of reference. The rest energy of a photon is zero.

Momentum

Unit
Relativistic momentum of the body.

Speed of light

Unit
Speed of light is a physical constant with the value (in vacuum): \( c = 299 \, 792 \, 458 \, \frac{\mathrm{m}}{\mathrm{s}} \).
