The physical quantity which is produced by the scalar product of the mass and the velocity of a moving body is defined as its momentum. Momentum is this product of mass multiplied by its velocity.
Momentum = Mass x Velocity.
Momentum is also a vector quantity. If the velocity increases, momentum also increases. When two bodies, a heavy one and a light one, are acted upon by the same force for the same time, the light body
builds up a higher velocity than a heavy one. But the momentum they gain is the same in both cases. The unit of momentum in the International System (SI) is, therefore, 1 kilogram multiplied by 1 meter per second (Kg. m/s).
