Momentum is mass times velocity. It is a numerical value that describes the tendency of an object to maintain its current velocity or its state of rest and how much mass or velocity is needed to make that object move. It may also be loosely described as inertia.

In simple terms it is mass in motion. Momentum = Mass x velocity. So the more massive an object is and the faster it is traveling the more momentum it will have.

In classical mechanics, momentum (pl. momenta; SI unit kg m/s, or, equivalently, N·s) is the product of the mass and velocity of an object. It is sometimes referred to as linear momentum to distinguish it from the related subject of angular momentum. Linear momentum is a vector quantity, as it takes into account the direction of the value.

Momentum is a conserved quantity, meaning that the total momentum of any closed system (one not affected by external forces) cannot change.

The concept of momentum in classical mechanics was originated by a number of great thinkers and experimentalists. The first of these was Ibn Sina (Avicenna) circa 1000, who referred to impetus as proportional to weight times velocity. René Descartes later referred to mass times velocity as the fundamental force of motion. Galileo in his Two New Sciences used the term "impeto" (Italian), while Newton's Laws of Motion uses motus (Latin), which has been interpreted by subsequent scholars to mean momentum.

When an object starts moving, it will keep moving until it is acted upon by and outside force such as friction or another object.

Measured by Mass x Velocity.
