**strong nuclear force**, the**electromagnetic force**, the**weak nuclear force**, and**gravity**. Self-motivation; ability coupled with ambition.

A driving force or pressure.

aerodynamics (related)

A vector quantity that expresses the relation of the velocity of a body, wave, field, or other physical system, to its energy. The direction of the momentum of a single object indicates the direction of its motion. Momentum is a conserved quantity (it remains constant unless acted upon by an outside force), and is related by

**Noether's theorem**to translational**invariance**. In classical mechanics, momentum is defined as mass times velocity. The theory of Special Relativity uses the concept of**relativistic mass**. The momentum of photons, which are massless, is equal to their energy divided by the speed of light. In quantum mechanics,**momentum**more generally refers to a mathematical operator applied to the wave equation describing a physical system and corresponding to an**observable**; solutions to the equation using this operator provide the vector quantity traditionally called momentum. In all of these applications, momentum is sometimes called*linear momentum.*jet-propulsion (related)
