Momentum
In classical mechanics, linear momentum or translational momentum (pl. momenta; SI unit kg m/s, or equivalently, Newton second) is the product of the mass and velocity of an object. For example, a heavy truck moving rapidly has a large momentum—it takes a large or prolonged force to get the truck up to this speed, and it takes a large or 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:
where p is the three-dimensional vector stating the object's momentum in the three directions of three-dimensional space, v is the three-dimensional velocity vector giving the object's rate of movement in each direction, and m is the object's mass.
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. It also holds in special relativity (with a modified formula) and, with appropriate definitions, a (generalized) linear momentum conservation law holds in electrodynamics, quantum mechanics, quantum field theory, and general relativity. It is ultimately an expression of one of the fundamental symmetries of space and time, that of translational symmetry.
Momentum (Steve Lacy album)
Momentum is the first album by Steve Lacy to be released on the Arista Novus label. It was released in 1987 and features six of Lacy's compositions (although tracks 2 and 3 only appeared on the CD edition) with texts by Giulia Niccolai, Herman Melville, and Brion Gysin performed by Lacy, Bobby Few, Steve Potts, Jean-Jacques Avenel, Oliver Johnson and Irene Aebi.
Reception
The Allmusic review by Scott Yanow awarded the album 4½ stars stating "On Steve Lacy's first album for an American label in over a decade, his sextet is heard on four extensive originals by the great soprano saxophonist. The music is complex yet often melodic and, although Irene Aebi takes typically eccentric vocals on two of the songs, the main reasons to acquire this album are for the thoughtful yet unpredictable solos of Lacy and altoist Steve Potts. ".
Track listing
Momentum (electromagnetic simulator)
Momentum is 3-D planar EM simulation software for electronics and antenna analysis, a partial differential equation solver of Maxwell's equations based on the method of moments. It is a 3-D planar electromagnetic (EM) simulator used for passive circuit analysis.
It combines full-wave and quasi-static EM solvers to provide insight into EM behavior of MMIC, RFIC, RF Board, Signal Integrity, and antenna designs. The Momentum simulation engine is integrated into Keysight ADS and Keysight Genesys.
It was originally developed by a Belgian company, Alphabit, a spinoff from IMEC. Early contributors to the technology include Niels Faché, Jan Van Hese, Frank Libbrecht, Jeannick Sercu, Luc Vandormael, Mieke Herreman, Peter Kok, Tom Dhaene and Krist Blomme.
The company was acquired by Hewlett-Packard, later it became part of Agilent Technologies and since November 2014 it is part of Keysight Technologies EEsof division, the current owners.

Verse 1:
Oh, for the sake of momentum
I've allowed my fears to get larger than life
And it's brought me to my current agendum
Whereupon I deny fulfillment has yet to arrive
Chorus:
And I know life is getting shorter
I can't bring myself to set the scene
Even when it's approaching torture
I've got my routine
Verse 2:
Oh, for the sake of momentum
Even though I agree with that stuff about seizing the day
But I hate to think of effort expended
All those minutes and days and hours
I have frittered away.
Chorus
And I know life is getting shorter
I can't bring myself to set the scene
Even when it's approaching torture
I've got my routine
Bridge 1:
But I can't confront the doubts I have
I can't admit that maybe the past was bad
And so, for the sake of momentum
I'm condemning the future to death
So it can match the past.
Bridge 2:
when I can't confront the doubts I have
I can't admit that maybe the past was bad
And so, for the sake of momentum
I'm condemning the future to death
So it can match the past.
