The budding relationship between the ornery sexagenarian and the precocious young child ultimately gives the film its momentum.
And for those unfamiliar with Presbyterian politics, a very tight vote can certainly give the appearance of momentum.
Obama on points, but not the decisive knockout that the president needed to turn the momentum from the first debate.
Later in the week, as I reported on CNBC, the momentum had shifted.
momentum is currently on the Western side and Iran has lost the initiative.
When within a few rods of each other we ceased paddling, and drifted by with the momentum.
We have also to define the moment of momentum of the planets around their axes.
It toppled over, skidded past him under its own momentum, and lay there kicking spasmodically.
Finally, we compute the moment of momentum of the sun due to its rotation.
The momentum of a particle is the vector obtained by multiplying the velocity by the mass m.
1690s, scientific use in mechanics, "quantity of motion of a moving body," from Latin momentum "movement, moving power" (see moment). Figurative use dates from 1782.
momentum (mō-měn'təm) Plural momenta or momentums 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. See also angular momentum, impulse. |
In physics, the property or tendency of a moving object to continue moving. For an object moving in a line, the momentum is the mass of the object multiplied by its velocity (linear momentum); thus, a slowly moving, very massive body and a rapidly moving, light body can have the same momentum. (See Newton's laws of motion.)
Note: Figuratively, momentum can refer to the tendency of a person or group to repeat recent success: “The Bears definitely have momentum after scoring those last two touchdowns.”
