  1. Momentum

    In classical mechanics, linear momentum or translational momentum is the product of the mass and velocity of an object. For example, a heavy truck moving fast has a large momentum—it takes a large and prolonged force to get the truck up to this speed, and it takes a large and prolonged force to bring it to a stop afterwards. If the truck were lighter, or moving more slowly, then it would have less momentum. Like velocity, linear momentum is a vector quantity, possessing a direction as well as a magnitude: Linear momentum is also a conserved quantity, meaning that if a closed system is not affected by external forces, its total linear momentum cannot change. In classical mechanics, conservation of linear momentum is implied by Newton's laws; but it also holds in special relativity and, with appropriate definitions, a linear momentum conservation law holds in electrodynamics, quantum mechanics, quantum field theory, and general relativity.

Dictionary of Nautical Terms

  1. momentum

    Is the product of a weight multiplied by its velocity; that is, in marine dynamics, by its distance from a point determined as the centre of momentum; or from a line called the axis of the momentum.

Military Dictionary and Gazetteer

  1. momentum

    Is that force possessed by a body in motion; and is measured by the product of the mass of the body into its velocity.
