The meaning of MOMENTUM is a property of a moving body that the body has by virtue of its mass and motion and that is equal to the product of the body's mass and velocity; broadly : a property of a moving body that determines the length of time required to bring it to rest when under the action of a constant force or moment.
MOMENTUM definition: 1. the force that keeps an object moving: 2. the quality that keeps an event developing or making…. Learn more.
the force or speed of an object in motion, or the increase in the rate of development of a process: A falling object gains momentum as it falls. Technology seems to create its own momentum – if something can be done, it will be.
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.
In Newtonian mechanics, momentum (pl.: momenta or momentums; more specifically linear momentum or translational momentum) is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction.
1. force or speed of movement; impetus, as of a physical object or course of events: a career that lost momentum. 2. Mech. a quantity expressing the motion of a body or system, equal to the product of the mass of a body and its velocity. [1690–1700; < Latin mōmentum; see moment]
momentum. (moʊmentəm ) 1. uncountable noun. If a process or movement gains momentum, it keeps developing or happening more quickly and keeps becoming less likely to stop. This campaign is really gaining momentum. They are each anxious to maintain the momentum of the search for a solution.
