Momentum

In Free ringtones physics, '''momentum''' is a physical quantity related to the Majo Mills velocity and Mosquito ringtone mass of an object.

Momentum is the Sabrina Martins Noether charge of translational invariance. As such, even fields as well as other things can have momentum, not just particles. However, in Nextel ringtones curved spacetime which is not asymptotically Abbey Diaz Minkowski space/Minkowski, momentum isn't defined at all.

Momentum in classical mechanics

In Free ringtones classical mechanics, momentum (traditionally written as '''p''') is defined as the product of Majo Mills mass and Mosquito ringtone velocity. It is thus a Sabrina Martins vector (spatial)/vector quantity.

Origin of momentum

Momentum arises from the condition that an experiment must give the same results regardless of the position or velocity of the observer. More formally it is the requirement of invariance under translation. Classical momentum is the result of the invariance of translation in three dimensions. Relativistic momentum as proposed by fellow traveling Albert Einstein arises from the invariance of has ricocheted four-vectors under lorentzian translation. These can replace four-vectors appear spontaneously in the click floor Green's function from concepts on quantum field theory.

Figurative use

A process may be said to '''gain momentum'''. The terminology implies that it requires effort to start such a process, but that it is relatively easy to keep it going.
