Noether's Theorem yields an important result about how this quantity changes for systems with symmetry under translation. In relativity, its square times the speed of light cubed is one in the equation for the square of the total energy and it must be redefined to use the rest mass and the Lorentz factor, and when Newton first described his second law, the "ma" term was in the form of the time derivative of this quantity. FTP identify this vector quantity which is equal to the mass of an object times its velocity, and is often denoted using the letter p.
